Abstract:
This invention relates to the preparation of polyamide block copolymers by sequential monomer addition. More particularly, it relates to catalysts capable of copolymerizing not only cyclic amides, but other monomers such as cyclic esters and epoxides as well, using sequential addition so as to produce useful and novel block copolymers.
