摘要： The instant invention relates to stabilizer compositions for thermoplastic polymers comprising a) at least one organophosphine, b) at least one 2-phenylbenzofuranone, and c) at least one sterically hindered piperidine based stabilizer (HAS), wherein the weight ratio of component a) to component b) to component c) is from 1:0.05:0.5 to 1:3:5. The instant compositions need an overall lower concentration as compared with the conventional phenol-containing formulations. In polyolefin articles, particularly in polyolefin-fibers, discoloration during processing and service life by both the formation of quinoid products and by action of NOx gases (gasfading) is avoided.
