What are polymers?

Back

Polymers are long chain molecules formed by joining together a large number of small molecules called monomers.

Front

What is addition polymerisation?

Back

Addition polymerisation is a chemical reaction in which unsaturated monomers are joined, forming a polymer.

Front

How are the names of addition polymers derived?

Back

The names of addition polymers are derived from the name of the monomer used.

Front

What is a repeating unit in a polymer?

Back

A repeating unit is the shortest section of a polymer chain which, if repeated, would yield the complete polymer chain (except for the end-groups).

Front

How can the structure of a polymer be represented?

Back

The structure of a polymer can be drawn given either the structure of the monomer or the repeating unit.
