Ring opening Polymerisation.

Ring opening Polymerisation

Ring opening Polymerisation have some features similar with addition and condensation polymerisation mechanism, they show at least one important different features from each of these polymerisation. In ring opening polymerisation the small molecules does not split up, while in condensation polymers it does. This Polymerisation is different from olefins polymerisation , in the sense that the driving force for this polymerisation is not derived from the loss of unsaturation of monomers.

This polymerisation generally gives linear compounds. These have generally same composition as that of the monomers. Not all Cyclic compounds undergo ring opening polymerisation. The general ring opening polymerisation is given by equation below.
