Elastomeric thermoplastic copolyether-esters endowed with improved thermo- oxidation resistance

摘要

The thermo-oxidation resistance of the elastomeric thermoplastic copolyether-esters is remarkably improved by the addition of a synergistic mixture consisting of an organo phosphite and a pentaerythritol phosphite.PPThe copolymer-esters thus compounded find use in the extrusion, blow and injection molding technologies.
