Presentation Transcript

  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:only1 type of monomeraddedtogether 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. 2. Condensation polymers : reactions with two or moredifferentmonomers linked A-B-A-B… • (nylon, polyurethane, and Dacron)

  6. GO TO: Macrogalleria of Polymer Fun • http://pslc.ws/macrog//maindir.htm • Go to (Level 1) • Go to three or four stores • List6different polymers (skip duplicates) • Follow the links for each polymer (Level 2) • Nameanddrawmonomer(s) • Drawpolymer • List the uses of each polymers

  7. EXAMPLE • Draw polymer • Name and draw monomer(s) • List the uses of each polymers

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