Syllabus Objectives – Macromolecules

Self Assessment Checklist

Macromolecules I can do this!
(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, the partial structure of nylon being represented as


and the partial structure of Terylene as


(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.
