Abstract:
The invention pertains generally to a polymer composition comprising a certain secondary anti-oxidant, that can also act as a polymer processing aid alone or in combination with another polymer processing aid.

Claim (Index 1):
A process to improve melt fracture resistance during melt processing of a synthetic polymer comprising the step of adding at least one homopolymer polyphosphite or copolymer polyphosphite of Formulas (I), (II) or (III) to the synthetic polymer: wherein\n each R 1 , R 2 , R 3  and R 4  can be the same or different and independently selected from the group consisting of C 12-20  alkyl, C 12-22  alkenyl, C 12-40  cycloalkyl, C 12-40  cycloalkylene, C 12-20  alkyl glycol ethers and Y\u2014OH as an end-capping group; \n each Y is independently selected from the group consisting of C 2-40  alkylene, C 7-40  cycloalkylene, C 3-20  alkyl glycol ethers, C 3-40  alkyl lactone, and \u2014R 7 \u2014N(R 8 )\u2014R 9 \u2014; \n R 7 , R 8  and R 9  are independently selected from the group consisting of C 1-20  alkyl, C 2-22  alkenyl, C 6-40  cycloalkyl, C 7-40  cycloalkylene and H; \n m is an integral value ranging from 1 to 100 inclusive; \n x is an integral value ranging from 2 to 1,000 with the proviso that when \u2014O\u2014Y is a C 3-20  alkyl glycol ether, x is an integral value no less than 7; and further wherein \n no more than two of R 1 , R 2 , R 3  and R 4  are terminated with an hydroxyl group; \n wherein\n each R 1 , R 2 , R 3 , R 4  and R 5  can be the same or different and independently selected from the group consisting of C 12-20  alkyl, C 12-22  alkenyl, C 12-40  cycloalkyl, C 12-40  cycloalkenyl, C 12-20  alkyl glycol ethers and A-OH and B\u2014OH as an end-capping groups; \n each A and B are different and independently selected from the group consisting of C 2-40  alkylene, C 7-40  cycloalkylene, C 3-20  alkyl glycol ethers, C 3-40  alkyl lactone, and \u2014R 7 \u2014N(R 8 )\u2014R 9 \u2014 wherein R 7 , R 8  and R 9  are independently selected from the group C 1-20  alkyl, C 2-22  alkenyl, C 6-40  cycloalkyl, C 7-40  cycloalkylene and H; \n m and n are integral values ranging from 1 to 100 inclusive; \n x and y are integral values ranging from 1 to 1,000 wherein x+y sum to at least 3, with the proviso that when \u2014O-A or \u2014O-B are C 3-20  alkyl glycol ethers, at least one of x or y is an integral value no less than 7; and further wherein \n no more than two of R 1 , R 2 , R 3 , R 4  and R 5  are terminated with an hydroxyl group; or \n where each R 1 , R 2 , R 3 , R 4 , R 5  and R 6  can be the same or different and independently selected from the group consisting of C 1-20  alkyl, C 2-22  alkenyl, C 6-40  cycloalkyl, C 7-40  cycloalkylene, C 3-20  methoxy alkyl glycol ethers, C 3-20  alkyl glycol ethers or Y\u2014OH (serving as an end capping moiety) for R 1 , R 2 , R 3 , R 4 , R 5  and R 6 ; Y is selected from the group consisting of C 2-40  alkylene, C 2-40  alkyl lactone, and C 2-40  cycloalkyl and further comprises C 2-20  alkyl glycol ethers when Y is in the polyphosphite backbone (e.g., ethylene, propylene, caprylactone, polyalkylene glycol); x is an integral value ranging from 8 to 1,000;\n z is an integral value ranging from 0 to 1,000 with the proviso that when z is 8 or greater, then x is an integral value ranging from 1 to 1,000; \n m is an integral value ranging from 1 to 20; w is an integral value ranging from 1 to 1,000; and combinations of formula (I) or Formula (II) or Formula (III).
