Solid compositions based on phosphites stabilised against hydrolysis for stabilising polyolefins.

摘要

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.
