WebPolymers are broken down into monomers via hydrolysis reactions, in which a bond is broken, or lysed, by addition of a water molecule. During a hydrolysis reaction, a molecule composed of multiple subunits is split in two: one of the new molecules gains a hydrogen atom, while the other gains a hydroxyl (-OH) group, both of which are donated by water. WebIn Addition Polymerization, there are three distinct steps. Initiation, propagation and finally termination. In condensation polymerization, there is no termination step. The end groups stay reactive through the complete method. Addition polymerization leads to homo-chain polymers whereas condensation polymerization leads to hetero-chain polymers.
