Methods of producing amine-terminated caprolactone polymers and uses of the produced polymers

摘要

A method for the preparation of an amine-terminated caprolactone polymer having at least two terminal ends with a primary amine located thereon, comprising the steps of : (a) using a polycarboxylic acid as an initiator in the ring opening polymerization of epsilon-caprolactone to produce a polycaprolactone polymer having at least two terminal ends with a carboxylic acid located thereon; and then (b) reacting the product of step (a) with a polyamine at a temperature of above 50°C to produce an amine-terminated polycaprolactone polymer.
