Step-Growth Polymerization Dacron and Nylon

This particular graft polymer is used to make rubber soles for shoes. [Pg.425]

Step-growth polymers are usually produced by a reaction between two monomers, each of which is at least difunctional. Many of them can be represented by the following overall equation [Pg.425]

Unlike chain-growth polymers, which grow by one monomer unit at a time, step-growth polymers are formed in steps (or leaps), often by reaction of one polymer molecule with another. The way this works is best illustrated with a specific example. [Pg.425]

Consider the formation of a polyester from a diol and a diacid. In the first step, the product will be an ester, with an alcohol group at one end and an acid at the other (eq. 14.25). [Pg.425]

A polyester is a step-growth polymer made from diacid and diol monomers. [Pg.425]
