REVISIONPOLYMERS

A molecule that consists of a large number of atomsMACROMOLECULE

POLYMERA large molecule composed of smaller monomer units covalently bonded to each other in a repeating pattern

MONOMERSmall organic molecules that can be covalently bonded to

each other in a repeating pattern

A chemical reaction in which monomer molecules join to form a polymer

POLYMERISATION

ADDITION POLYMERISATIONA reaction in which small molecules join to form very large molecules

by adding on double bonds

CONDENSATION POLYMERISATIONMolecules of two monomers with different functional groups undergo condensation reactions with the loss of small molecules, usually water

ADDITION POLYMERA polymer formed when monomers (usually containing a double

bond) combine through an addition reaction

CONDENSATION POLYMERA polymer formed by two monomers with different functional groups that are linked together in a condensation reaction in which a small

molecule, usually water, is lost

Identify monomers from given addition polymers..

ADDITION TO PRODUCE POLYTHENE

• Naphtha (petroleum) is obtained from crude oil• Catalytic cracking of naphtha (long-chain alkanes)

gives alkenes• Ethene (in gas form) undergoes polymerization to

form polyethylene.• The hot, liquid polyethylene is extruded through a

plate with holes. A blade cuts the (now solid) strings into smaller grains
