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.

Abstract: 1,2/POLYBUTADIENE IS CYCLIZED WITHIN 10 HOURS TO THE POINT OF COMPLETE ELIMATION OF VINYL UNSATURATION, AT CONCENTRATION IN LOWER ALKYL BENZENE IN THE RANGE 3%10% BY WEIGHT, USING A CATIONIC AGENT, ESPECIALLY BORON TRIFLUORIDE, TO PROMOTE THE CYCLIZATION. THE TEMPERATURE EMPLOYED IS AT MOST 105*C. AN ANTIOXIDANT SUCH AS A HINDERED POLYPHENOL IS INCLUDED IN THE CYCLIZATION REACTION MIXTURE.

Abstract: Substantially equimolar copolymers of a conjugated diene, such as butadiene, and a comonomer which is maleic anhydride or acrylonitrile can be prepared by copolymerizing the conjugated diene and the comonomer in an inert organic solvent in the presence of a Ziegler-type catalyst. The reaction proceeds rapidly at room temperature to yield a copolymer which is useful to form shaped articles.

Abstract: BUTADIENE COPOLYMERS OF MELTING POINT 30*-120*C. WITH THE MAJOR PROPORTION OF THE BUTADIENE CONTENT BEING COMBINED IN THE COPOLYMERS IN THE 1,2-FORM. THE COMONOMER IS A NON-CRYSTALLINE HYDROCARBON HAVING AT LEAST FIVE CARBON ATOMS IN THE MOLECULE AND HAVING A VINYL DOUBLE BOND CONJUGATED WITH AN OLEFINIC DOUBLE BOND. 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.
