ABSTRACT:
Block copolymers of the general formula --polycarbonate--G--polyether glycol-- wherein G is an ester aromatic carbonate and/or an ester-ester linkage, substantially free of aliphatic ether linkages are thermally stable in comparison with prior art block copolymers. They form compatible blends with a number of other thermoplastic resins to produce molded articles with improved resiliency. The block copolymers are produced from novel terminally functional end capped polyalkylene glycols.
