Homopolymer Copolymer
The polymers that are formed by the
polymerization of a single monomer are known as
homopolymers. In other words, the repeating units
of homopolymers are derived only from one
monomer. For example, polythene is a
homopolymer of ethane.		 The polymers whose repeating units
are derived from two types of
monomers are known as
copolymers. For example, Buna−S is
a copolymer of 1, 3-butadiene and
styrene.

Homopolyers: 

Polymers whose repeating structural units are dervied from only one type of monomer units are called homopolymers. For example, polythene, PVC, PAN etc.

Copolymers: 

Polymers whose repeating units are derived from two or more types of monomer molecules are called copolymers. For example, l3una – S, Buna – N, Nylon 6, 6 etc.
