What is the difference between a plastic and a polymer?
Plastics and natural materials such as rubber or cellulose are composed of very large molecules called polymers. Polymers are constructed from relatively small molecular fragments known as monomers that are joined together.
What is similar between plastics and polymers?
Plastics are a type of polymer.
