The instrinsic viscosity 
The instrinsic viscosity of these materials is related to their molecular weights via the Mark-Houwinkequation. Adding a dispersant to these compounds lowers the glass transition temperature. There are comb,brush and block variants of them. In almost all cases, these materials have a relatively broad molecularweight distribution which can be quantified using the polydispersity index. Depending on theirstereochemistry, they can classified as isotactic or syndiotactic. An aluminum and titanium material used tomake a type of these materials is called a Ziegler-Natta catalyst. Teflon and styrofoam are examples ofthese materials that include plastics. For 10 points, name these macromolecules formed by repeating a unitcalled a monomer.
