Abstract
An alkylphenol-free liquid polymeric phosphite is described of general Structure IV illustrated below wherein each R, R, Rand Rcan be the same or different and independently selected from the group consisting of Calkyl, Calkenyl, Ccycloalkyl, Ccycloalkylene, Cmethoxy alkyl glycol ethers, Calkyl glycol ethers, and or Y—OH; Y is selected from the group consisting of Calkylene, Calkyl lactone, —R—N(R)—R—, wherein R, Rand Rare independently selected from the group previously defined for R, R, Rand R, now further including H; m is an integral value ranging from 2 to 100 inclusive; and x is an integral value ranging from 1 to 1,000. The alkylphenol-free liquid polymeric phosphite is useful in reducing phosphite migration within polymers.
