A copolymeric polyphosphite is described: n nwherein each R 1 through 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—OH are different end-capping groups 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 —R 7 —N(R 8 )—R 9 —; wherein R 7 and through 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; m and n are integers from 1 to 100 inclusive, with various provisos. |
