Explain the difference between an addition polymer and a condensation polymer.
The difference between them is that an addition polymer has an addition reaction. Basically with an addition polymer forms when it doubles in bonds and each individual molecule breaks which then allows them to rebond themselves to other molecules in order that longer chains be formed.
Now the condensation polymer is formed a different way, by a condensation reaction. Basically when molecules will join together of course not all will combine like water so other than that the condensation polymer is a together reaction to simplify it
