ABSTRACT:
This invention relates to aliphatic polycarbonates including sequential copolymers based on cyclic aliphatic carbonates and esters and block copolymers of blocks of polymerised cyclic aliphatic carbonates and blocks of polymerised vinyl compounds stabilized against thermal degradation containing 0.01 to 3.0% by weight, based on polymer, of a compound of trivalent phosphorus.
