During the polymerisation of ethene, thousands of ethene molecules join together to make poly(ethene) - commonly called polythene. Ethene is known as the monomer. Poly(ethene) is the polymer.

Can ethene produce polymers?

Poly(ethene) is a polymer made from a very large number of ethene molecules combined together. The reaction is called a polymerisation reaction : ... poly(ethene) is the polymer.

Can alkenes form polymers?

Alkenes can be used to make polymers . Polymers are very large molecules made when many smaller, reactive molecules join together, end to end. ... The polymers formed are called addition polymers.
