Abstract: POLYESTERS ARE PREPARED BY POLYCONDENSATION OF A BIS(DIHYDRIC ALCOHOL) ESTER OF AROMATIC DICARBOXYLIC ACID USING A DEFINED CATALYST WHICH IS PRODUCED BY REACTING A HYDROXYL BEARING SUPPORT MATERIAL (E.G. ALUMINA) WITH A METAL COMPOUND. THE CATALYST MAY BE GRANULAR AND IN THIS FORM IS FILTERABLE FROM THE PRODUCT POLYMER.

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 DISPROPORTIONATION OF ALIPHATIC OLEFINICALLY UNSATURATED HYDROCARBON IN WHICH THE ALIPHATIC OLEFINICALLY UNSATURATED HYDROCARBON IS CONTACTED WITH AN INITIATOR WHICH IS THE PRODUCT OF REACTING UNDER ANHYDROUS AND OXYGEN-FREE CONDITIONS A TRANSITION METAL COMPLEX OF EMPIRICAL FORMULA

RMMXP

WITH A SUBSTANTIALLY INERT INORGANIC OXIDE MATRIX MATERIAL HAVING A HYDROXYLIC SURFACE WHICH IS FREE FROM ADSORBED WATER AND WHICH IS CAPABLE OF REACTING WITH THE TRANSITION METAL COMPLEX, WHEREIN M IS MOLYBDENUM, TUNGSTEN OR RHENIUM, R IS HYDROCARBON GROUP OR A SUBSTITUTED HYDROCARBON GROUP, X IS A MONOVALENT LIGAND AND M AND P ARE INTEGERS, M HAVING A VALUE OF FROM 2 UP TO THE HIGHEST VALENCE OF THE METAL M AND P HAVING A VALUE FROM 0 UP TO 2 LESS THAN THE VALENCE OF THE METAL M.
