Polyethylene More scientific Information: Polyethylene is an ethylene polymer. Polymers are large molecules prepared from relatively small chemical compounds called monomers. If only one monomer is used in the synthesis, as in the case of Polyethylene, the resulting polymer is a homopolymer.

Can polyethylene terephthalate react with alcohol? Polyethylene terephthalate is made from terephthalic acid and ethylene glycol. You can modify the plastic properties by adding another glycol such as cyclohexane dimethanol in… place of ethylene glycol. The properties of the plastic will be different due to the difference in size in the molecules.

Polymer Polymer nomenclature is generally based upon the type of monomer residues comprising the polymer. Polymers that contain only a single type of repeat unit are known as homopolymers, while polymers containing a mixture of repeat units are known as copolymers.Poly(styrene), for example, is composed only of styrene monomer residues, and is therefore classified as a homopolymer.olymer nomenclature is generally based upon the type of monomer residues comprising the polymer. Polymers that contain only a single type of repeat unit are known as homopolymers, while polymers containing a mixture of repeat units are known as copolymers.

polyethylene glycol 3350 GENERIC NAME: polyethylene glycol 3350. DRUG CLASS AND MECHANISM: Polyethylene glycol is an osmotic laxative. Polyethylene glycol works by retaining water in the stool, resulting in softer stools and more frequent bowel movements. Polyethylene glycol does not affect glucose and electrolytes in the body.

Polyurethanes The polymeric materials known as polyurethanes form a family of polymers which are essentially different from most other plastics in that there is no urethane monomer and the polymer is almost invariably created during the manufacture of a particular object.here is a fundamental difference between the manufacture of most polyurethanes and the manufacture of many other plastics. Polymers such as poly(ethene) and poly(propene) are produced in chemical plants and sold as granules, powders or films.

Plastics and Polymers Synthesis means that something is put together, and synthetic materials are made of building blocks that are put together in factories. The building blocks for making plastics are small organic molecules-molecules that contain carbon along with other substances.hen you polymerize ethylene you get a polyethylene resin. There are a number of polyethylene resins families that differ by such properties as density and molecular weight, and they can be made into a huge variety of plastic products. One of the most common is the plastic grocery bag.

- Addition Polymers. Addition polymers such as polyethylene, polypropylene, poly(vinyl chloride), and polystyrene are linear or branched polymers with little or no cross-linking. As a result, they are thermoplastic materials, which flow easily when heated and can be molded into a variety of shapes.ddition Polymers.

Synthetic Polymers and their Uses Synthetic polymers are often referred to as plastics, well-known are polyethylene and nylon. Polymers formed by a straightforward linking together of monomer units, with no loss or gain of material, are called addition polymers or chain-growth polymers. All of these are synthetic polymers.

Polyethylene The repeating unit within polyethylene in the most stable staggered conformation. Polyethylene (abbreviated PE) or polyethene (IUPAC name polyethene or poly(methylene)) is the most common plastic. The annual global production is around 80 million tonnes. Its primary use is in packaging (plastic bags, plastic films, geomembranes, containers including bottles, etc.). Many kinds of polyethylene are known, with most having the chemical formula (C2H4)n. PE is usually a mixture of similar polymers of ethylene with various values of n.
