What is homopolymer, and what is copolymer?

Synthetic polymers have structure which consists of repeated monomer units connected each other with chemical bonds, where a monomer means a unit component to form a polymer. If a polymer consists of only one kind of monomers then it is called a homopolymer, while a polymer which consists of more than one kind of monomers is called a copolymer.

Although polyacetal resin is a polymer made of successive oxymethylene units (-CH₂O-), second monomer units, i.e. comonomer units are added in the case of ...
