Chapter 29 - Polymerisation

when two molecules react together and produce a small molecule such as water or hydrogen chloride

amides and carboxylic acids amines and alcohols and haloalkanes all these molecules must have two functional groups

benzene-1,4-dioic acid and ethane-1,2-diol

polyesters and polyamides can be hydrolysed and are biodegradable

1,6-diaminohexane and hexane-1,6-dioic acid

benzene-1,4-diamine and benzene-1,4-dioic acid

because of the rigid chains and ability of the flat aromatic rings to pack together close, held by strong intermolecular forces

polyamides made from a single amino acid monomer, many different ones each amino acid has both an amine and carboxylic acid group

because the c-c and c-h bonds are highly unreactive and nothing in the natural environment will break these bonds easily

polyalkenes: because the level of carbon dioxide increases upon burning, and carbon monoxide can be produced other polymers may release toxic products such as styrene vapor

because they can be hydrolyzed by the addition of water however the reaction is very slow under normal conditions

crude oil is saved from being extracted and refined, this is important because it is non-renewable and an energy intensive process is plastics arent recycled they typically end up in landfills

plastics need to be collected, transported and sorted. this uses energy and manpower and is expensive

giant molecules made up of chains of smaller ones
