REVISION POLYMERS

MACROMOLECULE A molecule that consists of a large number of atoms POLYMER A large molecule composed of smaller monomer units covalently bonded to each other in a repeating pattern MONOMER Small organic molecules that can be covalently bonded to each other in a repeating pattern

POLYMERISATION A chemical reaction in which monomer molecules join to form a polymer ADDITION POLYMERISATION A reaction in which small molecules join to form very large molecules by adding on double bonds CONDENSATION POLYMERISATION Molecules of two monomers with different functional groups undergo condensation reactions with the loss of small molecules, usually water

ADDITION POLYMER A polymer formed when monomers (usually containing a double bond) combine through an addition reaction CONDENSATION POLYMER A 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

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 uses
