11.6 Macromolecules

(a) describe macromolecules as large molecules built up from small units, different macromolecules having different units and/or different linkages
(b) describe the formation of poly(ethene) as an example of addition polymerisation of ethene as the monomer
(c) state some uses of poly(ethene) as a typical plastic, e.g. plastic bags; clingfilm
(d) deduce the structure of the polymer product from a given monomer and vice versa
(e) describe nylon, a polyamide, and Terylene, a polyester, as condensation polymers and recognise the partial structures of nylon and Terylene
(Details of manufacture and mechanisms of these polymerisations are not required)
(f) state some typical uses of man-made fibres such as nylon and Terylene, e.g. clothing; curtain materials; fishing line; parachutes; sleeping bags
(g) describe the pollution problems caused by the disposal of non-biodegradable plastics
