- Linear, Branched, and Cross-linked Polymers. The term polymer is used to describe compounds with relatively large molecular weights formed by linking together many small monomers. Polyethylene, for example, is formed by polymerizing ethylene molecules.

Biodegradable Polymers Biodegradable polymers, as defined in this report, are bio-based or synthetic polymers that decompose to carbon dioxide and water under the agency of microorganisms in industrial or municipal compost facilities. A few of these polymers undergo decomposition in backyard compost bins or in soil, freshwater, or salt water.ther important biodegradable polymers include copolyesters such as polybutylene adipate terephthalate (PBAT) and polybutylene succinate adipate (PBSA), polycaprolactone (PCL), cellulose derivatives, polyglycolic acid (PGA), and polyhydroxyalkanoates (PHAs), including polyhydroxybutyrate (PHB) and related polymers.

Synthetic Organic Polymers Low Density Polyethylene (LDPE) polymers are among the most common types of synthetic organic polymers, which are often found in households. LDPE is a thermoplastic made from the monomer ethylene.

Polymer Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass relative to small molecule compounds produces unique physical properties, including toughness, viscoelasticity, and a tendency to form glasses and semicrystalline structures rather than crystals.

- A polyamide is a macromolecule with repeating units linked by amide bonds. Polyamides occur both naturally and artificially. Examples of naturally occurring polyamides are proteins, such as wool and silk.Artificially made polyamides can be made through step-growth polymerization or solid-phase synthesis yielding materials such as nylons, aramids, and sodium poly(aspartate) .Synthetic polyamides are commonly used in textiles, automotive applications, carpets and sportswear due to their high durability and strength.or the industrial production of synthetic polyamides with at least one aliphatic monomer (nylon polymers), the amide link is produced from the condensation reaction of an amino group and a carboxylic acid group, water is eliminated. For fully aromatic polyamides or 'aramids' e.g.

Polymers 3. Properties of Macromolecules. A comparison of the properties of polyethylene (both LDPE & HDPE) with the natural polymers rubber and cellulose is instructive. As noted above, synthetic HDPE macromolecules have masses ranging from 10 5 to 10 6 amu (LDPE molecules are more than a hundred times smaller).

Natural Polymers Most natural polymers are condensation polymers, and in their formation from monomers water is a by-product. Starch is a condensation polymer made up of hundreds of glucose monomers, which split out water molecules as they chemically combine.

Pika Although the pika inhabits regions where there are few other animals, the pika has a number of predators mainly due to it's small size. The weasel is the main predator of the pika, along with birds of prey, dogs, foxes and cats.ikas defend their territory by whistling to one another, and their large, rounded ears come in useful to hear the calls from competing pikas. Pikas are herbivorous animals and the pika therefore has a diet based on vegetation.

- Polymers are long chain molecules made of smaller, repeating unit molecules called “monomers”, similar to how beads (monomers) connected together form a necklace (polymer). Naturally occurring polymers include DNA, starch, wood and natural rubber. Synthetic polymers include polyethylene, polypropylene and polystyrene.

Making Plastics: From Monomer to Polymer While plastics encompass a large number of materials, polyethylene and polypropylene are two of the major plastic types found in many consumer goods, from car parts to shopping bags to water pipes. Several types of reactors can make polymers, including fluidized-bed, loop, autoclave, and tubular reactors.

Polymers and fibres Instead of the double bond that exists in a self-contained unit, these bonds are broken such that they form links with neighbouring alkenes to make a chain. An example of this is polyethene (sometimes known as polythene or polyethylene), which is a chain of many ethene molecules that looks like this: See image 1. There are several types of naturally occurring polymers such as plant-based cellulose and starch, which are both made of a type of sugar called glucose.

- Types of Biological Molecules – Monomers and Polymers. • Building blocks are monomers and macromolecules are polymers. • Monomers are simple sugars, amino acids, nucleotides, glycerol and fatty acids and they are. the building blocks for the Polymers - polysaccharides, proteins, nucleic acid (DNA & RNA), and triglyceride or fats. • Polymers are made by dehydration synthesis or the removal of the equivalent of water.

Plastics and Polymers Plastics are polymers, but polymers don't have to be plastics. The way plastics are made is actually a way of imitating nature, which has created a huge number of polymers. Cellulose, the basic component of plant cell walls is a polymer, and so are all the proteins produced in your body and the proteins you eat.ne of the most common is the plastic grocery bag. Polyethylene is made from just ethylene monomers-but it's also possible to create polymers from two or more different monomers. You can make hundreds of different polymers depending on which monomers and catalysts you use.

- In the last 30 years, plastics have become the most dominant engineering material for most products. We take. a brief look at the most common types of plastics, and how they are processed. All plastics are polymers; these polymers are further divided into two basic types: thermoplastics and. thermosets.

- Polymer properties and uses. Monomers monomer: A monomer is a simple molecule. can join together to form polymers polymers: Polymers are large molecules formed from many identical smaller molecules (monomers).. Additional polymers are formed from alkenes. lot of everyday items are made from polymers. Many of these polymers are not biodegradable-microbes cannot digest them and they take a long time to break down. Polymers are usually disposed of by burying them in landfill sites or burning them in incinerators.

- New types of polymers. Chemists are developing new types of polymers. Most polymers, including polyethene and polypropene, are not biodegradable. This means microorganisms cannot break them down, so they may last for many years in rubbish dumps.However, it is possible to include chemicals that cause the polymer to break down more quickly.olymers have recycling symbols like this one for PVC to show what they are. Many polymers can be recycled. This reduces disposal problems and the amount of crude oil used. But first the different polymers must be separated from each other.

SYNTHETIC POLYMERS Natural rubber comprises the molecules of the monomer 2-methyl-1,3-butadiene, also called isopropene, joined together to form a long chain. SYNTHETIC POLYMERS. • Synthetic polymer is a polymer that is manufactured in industry from chemical substances through the polymerisation process. Through research, scientists are now able to copy the structure of natural polymers to produce synthetic polymers. Plastics, synthetic fibres and elastomers are examples of synthetic polymers.

- When the same type of molecule component is used over and over in a much bigger molecule, the bigger molecules are called polymers. Starches, proteins, and nucleic acids are all different types of polymers.
