Question

Differentiate between homopolymers and copolymers.

Answer 1

Answer:

Definition

• Homopolymers consist of single species of repeating units.

• Copolymers consist of two or more type of repeating units.

Amount of Monomer Species

• Homopolymers have a single type of monomer.

• Copolymers have two or more types of monomers.

Chemical Structure

• Homopolymers usually have a simple structure.

• Copolymers have a complex structure.

Polymerization Process

• Homopolymers are formed through addition polymerization.

• Copolymers are formed through condensation polymerization.

Examples

• Homopolymers include PVC, polyethylene, polypropylene, polystyrene, polytetrafluoroethylene, and poly(methyl methacrylate).

• Copolymers include poly (vinyl acetate), poly (ethylene oxide), poly(ethylene terephthalate) and poly(hexamethylene sebaacamide).
