Description: In this video, we look at addition polymers. First we explore what is meant by an addition polymer, a monomer and the repeating unit. I give you several addition polymers and ask you to work out the monomer and repeating unit. We then finish by looking at the role of plasticisers. 00.00 Objectives 00.36 How do we form an addition polymer? 00:52 What are the conditions for addition polymerisation? 01.16 How do we name addition polymers? 01.41 Why are addition polymers unreactive molecules? 02.22 How do we draw the repeating unit? 03.20 How do we work out the monomer from the polymer? 03.55 A question for you on poly(chloroethene) 04.14 A question for you on poly(propene) 04.31 A question for you on poly(phenylethene) 05.11 What is a plasticiser? 05.35 How does a plasticiser work?
