Polymers

Define polymer

• circular molecule made with many repeating units

• short molecule made of a few repeating units

• long, chain-like molecule made of repeating units

• chain-like molecule that contains hydrogen and oxygen

What is the process to make long polymer (plastic) chains?

• Fractional Distillation

• Curing

• Fracking

• Polymerization

What kind of chemical bonds create polymers?

• ionic

• covalent

• hydrogen

• metallic

Once formed, it can be heated and reformed over and over again

• thermoset

• thermoplastic

• elastomer

• kevlar
