ABSTRACT:
A process for modifying a poly(alkylene carbonate) polyahl, which comprises reacting the poly(alkylene carbonate) polyahl, with at least one modifier having at least one active hydrogen moiety or cyclic anhydride, optionally in the presence of a catalyst under transesterification conditions to form a modified poly(alkylene carbonate) polyahl wherein the modifier is chemically bonded to the backbone of the poly(alkylene carbonate) polyahl.
