Abstract: Polyolefins are stabilized with mixtures of certain bisphenol alkanoic acid esters or amides with organic phosphites. In the examples the stabilizers used are selected from 3,3-bis-(4-hydroxy-3-methyl phenyl) butanoic acid dodecyl ester, 4,4-bis-(4-hydroxyphenyl)-pentanoic acid dodecyl ester, octyldiphenyl phosphite, triphenyl phosphite and tridodecyl phosphite.

Abstract: 1. Solid phosphorous acid ester preparations having an improved stabilizing effect in polyolefin plastic materials, comprising from 20 to 97 weight % of a known, solid organic phosphorous acid ester stabilizer for a plastic material, and form 80 to 3 weight % of a wax selected from the group consisting of natural or partially synthetic ester waxes, amide waxes, esters of polyolefin wax oxidates and wax-like esters of long chain phosphorous acids.
