Abstract: POLYBUTADIENE COMPOSITIONS OF MELTING POINT 50*-100* C. WITH THE MAJOR PROPORTION OF THE BUTADIENE CONTENT BEING COMBINED IN THE 1,2 FORM. THE CO-INGREDIENT IS RUBBERY, AMORPHOUS BUTADIENE POLYMER HAVING VINYL DOUBLE BONDS AND INTERNAL DOUBLE BONDS. THE PROCESS OF MAKING EMPLOYS AS CATALYST A COMPLEX OF A COBALT COMPOUND WITH BUTADIENE OR OPEN CHAIN BUTADIENE DIMER AND WITH AN ORGANO METALLIC COMPOUND OF ZINC, LITHIUM OR ALUMINUM; AND A CATALYST MODIFIER OF FUMARIC ACID ESTER OR MALEIC ACID ESTER. THE COPOLYMERS ARE FORMULATED TO MOLDING COMPOUNDS WHICH CAN BE CURED RAPIDLY AND USED IN TRANSFER MOLDING.
