Abstract

Abstract The high polymerization degree polyetheresteramides without any gelated materials and with superior color tones are obtained in a short time through the polycondensing interaction carried out between (A) one or more than two polyamide forming components selected from lactams and aminocarboxylic acids as well as the salts of substantially-equal quantities of diamines and dicarboxylic acid and (B) the polyetherester forming components consisting of the substantially-equal quantities of dicarboxylic acids and poly(alkylene oxide) glycols in the presence of 0.001 to 0.5 percent by weight of the mixtures composed of antimony oxides/organic tin compounds at the ratios of 80/20 to 30/70 by weight and more preferably in the co-presence of 0.0005 to 0.5 percent by weight of phosphoric compounds.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 99 words
The processes for producing polyetheresteramides wherein one or more than two polyamide forming components (A) selected from lactams and aminocarboxylic acids as well as the salts of the substantially-equal quantities of diamines and dicarboxylic acids and (B) the polyetherester forming components consisting of substantially-equal quantities of dicarboxylic acids and poly(alkylene oxide) glycols are subjected to polycondensation while melted, which is characterized in that said polycondensation is carried out in the presence of 0.001 to 0.5 percent by weight per said polyetheresteramides of the mixtures composed of antimony oxides/organic tin compounds at the ratios of 80/20 to 30/70 by weight.
Claim 2
Dependent Claim 99 words
The processes for producing polyetheresteramides wherein one or more than two polyamide forming components (A) selected from lactams and aminocarboxylic acids as well as the salts of the substantially-equal quantities of diamines and dicarboxylic acids and (B) the polyetherester forming components consisting of substantially-equal quantities of dicarboxylic acids and poly(alkylene oxide) glycols are subjected to polycondensation while melted, which is characterized in that said polycondensation is carried out in the presence of 0.001 to 0.5 percent by weight per said polyetheresteramides of the mixtures composed of antimony oxides/organic tin compounds at the ratios of 80/20 to 30/70 by weight.
