ESLATOMERIC THERMOPLASTIC COPOLYETHER-ESTERS ENDOWED WITH IMPROVED THERMO-OXIDATION RESISTANCE

摘要

The thermo-oxidation resistance of the elasto=meric thermoplastic copolyether-esters is remarkablyimproved by the addition of a synergistic mixture con=sisting of an organo phosphite and a pentaerythritolphosphite.The capolyether-esters thus compounded find usein the extrusion, blow and injection molding technolo=gies.
