उत्तर
| 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. | The polymers whose repeating units are derived from two types of monomers are known as copolymers. |
| Example: polythene is a homopolymer of ethene. | Example: Buna-S is a copolymer of 1,3-butadiene and styrene. |
