1. Starter What is the difference between an addition and condensation polymer? Write an equation for the polymerisation of two molecules of 3-hydroxypropanoic acid, HOOCCH 2 CH 2 OH

2. Addition Polymerisation L.O.: Compare condensation polymerisation with addition polymerisation. Suggest the type of polymerisation from a given monomer or pair of monomers, or a given section of a polymer molecule. Identify the monomer(s) required to form a given section of a polymer (and vice versa).

7. L.O.: Describe the acid and base hydrolysis of polyesters and polyamides. Outline the role of chemists in the development of degradable polymers. Explain that condensation polymers may be photodegradable and may be hydrolysed. Breaking down condensation polymers

8. Biodegradable polymer is a polymer that breaks down completely into carbon dioxide and water. A degradable polymer: is a polymer that breaks down into smaller fragments, when exposed to light, heat or moisture.

20. Week 9 © Pearson Education Ltd 2009 This document may have been altered from the original Explain that the synthesis of pharmaceuticals often requires the production of a single optical isomer. Explain that synthetic molecules often contain a mixture of optical isomers, whereas natural molecules often have only one optical isomer. Explain that the synthesis of a pharmaceutical that is a single optical isomer increases costs, reduces side effects and improves pharmacological activity. Describe strategies for the synthesis of a pharmaceutical with a single optical isomer.
