1 Polymers

2 Describe the process of polymerization and identify important natural and synthetic polymers Additional KEY Terms monomer

3 Polymers are very large molecules made of many smaller repeating units. ‘poly’ – many ‘mer’ – part. Each individual part is called a monomer. Polyethylene – “plastic wrap’

4 Two main Polymerization reactions: 1. Addition polymers: only 1 type of monomer added together to form a long chain polymer. Monomer is usually an alkene. (Polypropylene, Teflon, synthetic rubbers) Usually requires an initiator – to kick start the reaction (disrupts double bonds)

5

6 2. Condensation polymers : reactions with two or more different monomers linked A-B-A-B… (nylon, polyurethane, and Dacron)

7

8  GO TO: Macrogalleria of Polymer Fun Go to (Level 1) Go to three or four stores List 6 different polymers (skip duplicates) Follow the links for each polymer (Level 2) Name and draw monomer(s) Draw polymer List the uses of each polymers

9 EXAMPLE Draw polymer Name and draw monomer(s) List the uses of each polymers NAMEMONOMERPOLYMERUSES

10 CAN YOU / HAVE YOU? Describe the process of polymerization and identify important natural and synthetic polymers Additional KEY Terms monomer
