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.

Elastomeric thermoplastic copolyether-esters endowed with improved

A rheological and mechanical properties and the ageing resistance of the elastomeric thermoplastic copolyesters are remarkably improved by the addition of a synergistic mixture of a polycarbodiimide and a quinolinic antioxidant. The copolyesters containing the above synergistic mixture find use in the extrusion technology. Said copolyesters, when they are subjected to a heat treatment at a temperature lower than 150.degree. C., increase the melt viscosity so that they can be used in the blow-molding technology.

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. The copolymer-esters thus compounded find use in the extrusion, blow and injection molding technologies.

Hot melt adhesive compositions based on polyesters

Segmented thermoplastic copolyesters having elastomeric properties, containing from 25% to 80% by weight of short-chain polyester units derived from dicarboxylic acids and a diol, and from 20 to 70% by weight of long-chain polyester units derived from dicarboxylic acids and poly(alkylene oxide)-glycols in which at least 10% by weight of the poly-(alkylene oxide)-glycols has a molecular weight lower than 300, and a C/O ratio within the range of from 1.8 to 4.3.
