Elastomeric thermoplastic copolyetheresters having improved thermal and hydrolytic stabilities

摘要

The thermal and hydrolytic stabilities of elastomeric thermoplastic copolyether-esters are significantly improved by the addition of a synergistic mixture of tris(hydroxybenzyl)benzene and bis(alkylphenyl)pentaerythritol diphosphite. The copolyether-esters thus compounded can be used to particular advantage in extrusion, blow moulding and injection moulding technologies.
