Patent ID: 8008385

Claim:
A composition comprising a phosphite composition, which phosphite composition consists of: (a) from 25 to 80 weight percent of a tris(dialkylaryl)phosphite; (b) from 15 to 50 weight percent of a bis(dialkylaryl)monoalkylaryl phosphite; (c) from 3 to 25 weight percent of a bis(monoalkylaryl)dialkylaryl phosphite; (d) from 0.1 to 6 weight percent of a tris(monoalkylaryl)phosphite; (e) from 0 to 5 weight percent other phosphites wherein dialkylaryl in (a), (b), (c) and (d) is dibutylphenyl or diamylphenyl and monoalkaryl in (a), (b), (c) and (d) is butylphenyl or amylphenyl, weight percent is based on the total weight of all phosphites in the phosphite composition, and wherein the phosphite composition is a solid at ambient conditions melting in a temperature range of from greater than 30° C. to less than 170° C.
