Abstract: 1. IN A PROCESS FOR THE PRODUCTION OF HIGHLY POLYMERIC POLYESTER BY POLYCONDENSATION OF A POLYCONDENSABLE MATERIAL AT LEAST 85 MOLE PERCENT OF WHICH CONSISTS OF AT LEAST ONE BIS(DIHYDRIC ALCOHOL) ESTER OF AN AROMATIC DICARBOXYLIC ACID, OR AN OLIGOMER THEREOF, THE IMPROVEMENT COMPRISING THE EMPLOYMENT AS A CATALYST OF A CATALYTIC AMOUNT OF A COMPOSITION CONSISTING ESSENTIALLY OF A METALLIC COMPONENT AND AN ORGANIC COMPONENT, THE METALLIC COMPONENT BEING A METAL OXIDE OR A METAL SALT CONTAINING A WEAKLY ACIDIC ANION, SAID METAL IS SELECTED FROM THE GROUP CONSISTING OF ZINC, MANGANESE, ALUMINUM, LANTHANUM, COBALT, CALCIUM AND CADIUM, AND THE ORGANIC COMPONENT BEING A SIMPLE OR POLYMERIC COMPOUND OF THE STRUCTURE

X3-O-Z(=O)(-X1)-X2

WHERE X1 IS -R OR -OR,X2 IS -R,X3 IS-H OR -R,Z IS AN ATOM OF A GROUP VB ELEMENT OF THE PERIODIC TABLE HAVING AN ATOMIC NUMBER GREATER THAN 7, AND EACH R, WHICH MAY BE THE SAME OF DIFFERENT, IS A MONOVALENT HYDROCARBON GROUP, WHEREIN THE MOLECULAR WEIGHT OF AT LEASTT ONE OF THE GROUPS R ATTACHED DIRECTLY TO THE ATOM Z IS GREATER THAN 145.

Abstract: 1. A PROCESS FOR THE PRODUCTION OF HIGHLY POLYMERIC POLYMER BY THE POLYCONDENSATION OF A POLYCONDENSABLE MATERIAL, AT LEAST 85 MOL PERCENT OF WHICH CONSISTS OF AT LEAST ONE BIS8DIHYDRIC ALCOHOL) ESTER OF AN AROMATIC DICARBOXYLIC ACID OR AN OLIGOMER THEREOF, THE POLYCONDENSATION BEING EFFECTED IN THE PRESENCE, AS CATALYST, OF A MIXTURE OF (A) A METALLIC COMPONENT WHICH IS A WEAK ACID SALT OF ZINC, MANGANESE OR ALUMINUM OR ZINC OXIDE AND (B) AN ORGANIC COMPONENT WHICH IS A COMPOUND OF THE STRUCTURE

X3-O-Z(-X1)(-X2)=O

WHEREIN Z IS SELECTED FROM THE GROUP CONSISTING OF ARSENIC AND PHOSPHORUS, X1 IS -R OR -OR, X2 IS X3 IS -H OR -R, AND EACH R, WHICH MAY BE THE SAME OR DIFFERENT, IS A SATURATED ALIPHATIC OR AROMATIC HYDROCARBON, IN WHICH PROCESS THE AMOUNT OF EACH COMPONENT IS 0.0001 TO 0.05% BY WEIGHT OF THE POLYCONDENSABLE MATERIAL.
