Abstract
A phosphite composition comprising at least two of a tris(diamylaryl) phosphite, a tris(monoamylaryl) phosphite, a bis(diamylaryl)monoamylaryl phosphite, and a bis(monoamylaryl)diamylaryl phosphite. The inventive phosphite composition is a liquid at ambient conditions.
Claims18
A phosphite composition consisting essentially of:
- from 0 to 20 weight percent based on the total weight of the composition of a tris(diamylaryl) phosphite;
- from 20 to 70 weight percent based on the total weight of the composition of a tris(monoamylaryl) phosphite;
- from 2 to 20 weight percent based on the total weight of the composition of a bis(diamylaryl)monoamylaryl phosphite;
- and
- from 15 to 60 weight percent based on the total weight of the composition of a bis(monoamylaryl)diamylaryl phosphite,
- wherein the composition is a liquid at room temperature and atmospheric pressure.

An additive composition consisting essentially of:
- from 1 to 4 weight percent based on the total weight of the additive composition of a phenol;
- from 0 to 20 weight percent based on the total weight of the additive composition of a tris(diamylaryl) phosphite;
- from 20 to 70 weight percent based on the total weight of the additive composition of a tris(monoamylaryl) phosphite;
- from 2 to 20 weight percent based on the total weight of the additive composition of a bis(diamylaryl)monoamylaryl phosphite;
- and
- from 15 to 60 weight percent based on the total weight of the additive composition of a bis(monoamylaryl)diamylaryl phosphite,
- wherein the composition is a liquid at room temperature and atmospheric pressure.
