ELASTOMERIC THERMOPLASTIC COPOLYETHER-ESTERS ENDOWED WITH IMPROVED THERMAL AND HYDROLITIC STABILITIES

摘要

The thermal and hydrolytic stabilities of the elastomeric thermo- plastic 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.
