What special property does a shape memory polymer have?

Give a definition of a polymer. Very large long chain molecule made up of lots of small repeating units called monomers

What is the raw material for making plastics?Crude oil

Why is it important to recycle plastics?They are made from crude oil, which is a finite resource. We are running out of landfill space
