derived from one species of (real, implicit or hypothetical) monomer
Many polymers are made by the mutual reaction of complementary monomers. These monomers
can readily be visualized as reacting to give an 'implicit monomer', the homopolymerization of which would give the actual product, which can be regarded as a homopolymer. Common
examples are poly(ethylene terephthalate) and poly(hexamethylene adipamide).
Some polymers are obtained by the chemical modification of other polymers such that the structure of the macromolecules that constitute the
resulting polymer can be thought of as having been formed by the homopolymerization of a hypothetical monomer. These polymers can be regarded as homopolymers. Example: poly(vinyl alcohol).
