    I've got to answer the following exam question:

    "Discuss and explain the differences in behaviour that you would expect to observe between poly(n-butyl acrylate) and poly(n-butyl methacrylate) on thermal degradation in a vacuum. In your answer, you should show the main features of the chemistry of degradation of each polymer."
    [13 marks]

    So far I have deduced that poly(n-butyl acrylate) cannot be degraded by depropagation because the x site is a hyrdrogen atom. Therefore is must degrade by homolytic scission. However, I'm not sure what type of homolytic scission it undergoes. Can anyone help me understand what mechanism is involved in the degradation of this polymer.
    I've also found that poly(n-butyl methacrylate) can be degraded by depropagation as neither X nor Y site and hydrogen atoms. I know the full mechanism of this polymer and haver written it in my answer.

    Is there anything additional I can say to help get more marks.

    Thanks.
