In this respect it is useful to distinguish several ways in which different monomeric units might be incorporated in a polymeric molecule. I 2503 The following normalization relations hold. A copolymer is a polymer formed when two or more different types of monomer are linked in the same polymer chain as opposed to a homopolymer where only one monomer is used.

The examples are terylene dacron nylon 6 6 etc. Chemistry questions and answers. The union of the homopolymer subunits may require an intermediate non-repeating subunit known as a junction blockDiblock copolymers have two distinct blocks.

Copolymers can be defined by their ability to be an elastomer. A copolymer is a polymer that is made up of two or more monomer species.
