Abstract
The thermal and hydrolytic stabilities of the elastomeric thermoplastic copolyether-esters are remarkably improved by the addition of a synergistic mixture consisting of an tri (hydroxybenzyl) benzene and of a bis (alkyl-phenyl) pentaerythritol diphosphite. The copolyether-esters thus compounded find use in the extrusion, blow and injection molding technologies.
