when 2 or more molecules produce 1 molecule |
|

|
Why are condensaiton polymers degradable? |
They have polar bonds that are susceptable to nucleophillic attack by eg water and therefore will break down |
|
|
Why aren't polyalkenes degradable? |
Polyalkenes don't have polar bonds therefore don't break down |
