Unit 28 Addition polymers

Addition polymer

Addition polymer - polymers that are made by addition polymerization

Addition polymerization

Addition polymerization - a reaction in which monomer molecules join together repeatedly to form polymer molecules

Asbestos

Asbestos - naturally occuring silicate minerals

Carbohydrate

Carbohydrate - large biologcal molecules with mainly carbon, hydrogen and oxygen

Cellulose

Cellulose - large biologcal molecules with the general formula (C6H10O5)n

High density polythene

High density polythene - polythene that contains much longer polymer chains, does not have branching and is more closely packed

Low density polythene

Low density polythene - polythene that contains short polymer chains with a considerable degree of branching and has an open structure

Man-made polymer

Man-made polymer - polymer that does not exist naturall in nature

Monomer

Monomer - a compound whose molecules join together repeatedly to form polymer molecules

Natural polymer

Natural polymer - polymer that exist naturally in nature

Perspex

Perspex - polymer that formed by addition polymerization of methyl-2-methylpropenate

Plastic

Plastic - a wide range of modable organic solid 

Polymer

Polymer - compounds that consist of very large molecules formed by joining together many small molecules repeatedly

Polymerization

Polymerization - the process of repeatedly joining together many small molecules to form very large molecules

Polypropene

Polypropene - polymer that formed by addition polymerization of propene

Polystyrene

Polystyrene - polymer that formed by addition polymerization of styrene

Polyvinyl chloride

Polyvinyl chloride - polymer that formed by addition polymerization of vinyl chloride

Protein

Protein - large biologcal molecules with long chains of amino acid

Rayon

Rayon - manufactured regenerated cellulose fiber

Repeating unit

Repeating unit - the smallest part of a polymer molecule, and the whole polymer structure can be obtained by repeating it

Sythetic polymer

Sythetic polymer - man-made polymer that is made from small molecules of monomers

Thermoplastic

Thermoplastic - plastics that can be melted or softened by heat at relatively low temperatures
