Abstract
A thermoplastic molding composition having improved release properties is disclosed. The composition contains a polycarbonate and an additive amount of an epoxy conforming structurally to ##STR1## where R is a member selected from the group consisting of glyceryl and trimethyl propyl radicals, x is 0 to 20 and R' is a C.sub.1-4 alkyl radical.
Claims10
A thermoplastic molding composition consisting essentially of carbonate polymer and about 0.1 to 2 percent relative to the weight of said composition of a mold releasing compound conforming structurally to ##STR8## where R is a member selected from the group consisting of ##STR9## x is 0 to 20 and R' is a C.sub.1-4 alkyl radical, said composition exhibiting improved mold release as compared to a corresponding composition which contains no such compound.
