Organic oxalate plasticized polycarbonate composition

Claim 1

A plasticized polycarbonate composition comprising in admixture a high molecular weight aromatic carbonate polymer prepared by reacting a dihydric phenol with a carbonate precursor and having an I.V. of 0.40 to 1.0 dl./g. in methylene chloride at 25° C., and a minor amount of an organic oxalate of the following formula: ##STR15## wherein R and R" are independently selected from the group consisting of C 1 to C 30 alkyl, aryl of 6 to 14 carbon atoms and substituted aryl wherein the substituents are C 1 to C 30 alkyl, halogen, C 1 to C 30 alkoxy, aryloxy of 6 to 14 carbon atoms, alkylthio of 1 to 30 carbon atoms, arylthio of 6 to 14 carbon atoms, R' is selected from the group consisting of C 1 to C 30 alkylene, arylene of 6 to 14 carbon atoms, alkarylene of 7 to 30 carbon atoms, aralkylene of 7 to 30 carbon atoms and ##STR16## wherein W is selected from the group consisting of: ##STR17## wherein A is ##STR18## and R 4 is hydrogen of C 1 -C 4 alkyl; R is independently selected from the group consisting of hydrogen, C 1 -C 15 alkyl, aryl of 6-14 carbon atoms and substituted aryl wherein the substituents are C 1 -C 5 alkyl; (b) --CH 2 CH 2 --; (c) --CH 2 B-CH 2 --; wherein B is C 1 -C 16 alkylene or arylene of 6 to 14 carbon atoms; ##STR19## wherein a is an integer of 3 to 15; (e) --O--; (f) --S--; ##STR20## X and Y are independently selected from the group consisting of halogen and C 1 -C 12 alkyl; n is 0 or 1.
