WebPolymers can be broken down into two categories by how they form: addition polymers and condensation polymers. 3.6.1. Addition Polymers ¶. Addition Polymers form from the reaction of a single monomer with itself (for example, ethene to polyethene). In this process the double bond is broken and becomes a single bond.
