A composition at least two different phosphites, one of which is derived from an alkylated m-cresol, wherein the composition is a liquid at ambient conditions. The other phosphites may be derived from alkylated cresol, alkylated phenol or other alkylated hydroxyaryl compounds. The cresol may be mono-alkylated or di-alkylated with a C1-C18 alkyl group.

A phosphite composition comprising at least two of a tris(dibutylaryl) phosphite, a tris(monobutylaryl) phosphite, a bis(dibutylaryl)monobutylaryl phosphite, and a bis(monobutylaryl)dibutylaryl phosphite. The inventive phosphite composition is a liquid at ambient conditions. The inventive phosphite is a reaction product of a phorsphous trihalide with an alkylate composition having a molar ratio of monobutylaryl alkylate to dibutylaryl alkylate that is higher than 2:1 and equal to or lower than 5:1.

The invention is directed to various alkylaryl phosphite compositions that ideally are suitable for use as secondary antioxidants in polymers. In one aspect, the phosphite composition comprises a tris(monoalkylaryl)phosphite in an amount from 51 to 95 weight percent; and at least one of: a bis(monoalkylaryl)dialkylaryl phosphite; a bis(dialkylaryl)monoalkylaryl phosphite; and a tris(dialkylaryl) phosphite. The inventive phosphite composition is a solid at ambient conditions. The invention also relates to alkylate compositions and processes for forming such alkylate compositions and such phosphite compositions.

A composition comprising at least two different alkylaryl phosphites, wherein some alkyl groups have a different number of carbon atoms than other alkyl groups and wherein the composition is a liquid at ambient conditions.
A crystalline polyolefin composition is described, comprising a crystalline polyolefin, a dibenzylidenesorbitol-type compound and a cyclodextrin, the amount of said dibenzylidenesorbitol-type compound being 0.01 to 1 part by weight per 100 parts by weight of the crystalline polyolefin, the amount of said cyclodextrin being 0.001 to 1,000 parts by weight per 100 parts by weight of the dibenzylidenesorbitol-type compound, from which formed articles having both excellent transparency and greatly improved odor-non-emitting properties can be obtained.
