2 Polymers are very large molecules made of many smaller repeating units. ‘poly’ – many ‘mer’ – part.Each individual part is called a monomer.Polyethylene – one type of ‘plastic’
3 (Polypropylene, Teflon, synthetic rubbers) Two main Polymerization reactions:1. Addition polymers: 1 type of monomer units 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).
4 (nylon, polyurethane, and Dacron) 2. Condensation polymers : reactions with two or more different monomers.(nylon, polyurethane, and Dacron)
6 Large molecules with repeating units monomers. Addition polymers - monomers unit adds together.Polymerization requires an initiator.Condensation polymers - two or more different monomers that results in the formation small molecules like water and ammonia.
