Question

Explain how intra/intermolecular forces within polymers and between polymer chains affect the shape of the polymer.

Answer 1

A molecule is a group of atoms connected by covalent bonds. Chemical reactions are required to form or break covalent bonds. Weaker attractions often form between molecules, encouraging them to stick together in groups. The weaker attractions are called secondary bonds or intermolecular forces. These can be overcome by adding heat or dissolving in a liquid. The functional groups on a polymer determine the type(s) and strength of its secondary bonds.
