Abstract: 1,2-BUTADIENE POLYMER HAVING AT LEAST 80% OF THE BUTADIENE CONTENT COMBINED THEREIN IN THE 1,2 FORM IS USED TOGETHER WITH A PEROXY CURING AGENT TO PRODUCED A MOLDING COMPOSITION. THE POLYBUTDIENE CAN BE IN A NORMALLY GRANULAR, CRYSTALLINE FORM OR IN NON-CRYSTALLINE FORM. THE COMPOSITION CURES AT GOOD RATE EVEN WHEN ANTIOXIDANT TO INHIBIT PREMATURE CURING IS INCLUDED IN THE COMPOSITION. A HEAT DISTORTION TEMPERATURE OF AT LEAST 250*C. CAN BE OBTAINED. CONVENTIONAL INGREDIENTS OF MOLDING COMPOUNDS SUCH AS FILLERS AND MOLD LUBRICANTS CAN BE INCORPORATED WITH THE COMPOSITION. THE COMPOSITION CAN BE WORKED WITHOUT CURING UP TO A TEMPERATURE OF ABOUT 150* C. AND CURED AT HIGHER TEMPERATURES.

Abstract: VAPOR PHASE POLYMERIZATION OF BUTENE-1 USING ZIEGLERNATTA STEREOREGULATING CATALYST WITH DIETHYL ALUMINUM CHLORIDE AS CO-CATALYST. MAINTAINING INITIAL TEMPERATURE LESS THAN ABOUT 26*C. AFFORDS POWDER OR GRANULAR POLY-(BUTENE-1) RESIN OF HIGH ISOTACTICITY, SUITABLE FOR POWDER MOLDING. AFTER INITIAL PHASE OF POLYMERIZATION (WHEN SUFFICIENT POLYMER HAS BEEN FORMED TO FILL AT LEAST ABOUT 10% OF THE REACTOR VOLUME), TEMPERATURE AND PRESSURE CAN BE RAISED IN ORDER TO INCREASE REACTION RATE WITHOUT CAUSING AGGLOMERATION OF PRODUCT. MOLECULAR WEIGHT OFPOLY(BUTENE-1) IS CONTROLLED WITHOUT AFFECTING GRANULARITY BY SUPPLYING HYDROGEN INTO THE REACTION MEDIUM.

Abstract: BLENDS OF PETROLEUM WAX WITH (1) FROM 1 TO 20 WT. PERCENT OF POLYBUTENE-1 HAVING AN AVERAGE MOLECULAR WEIGHT OF ABOUT 50,000 TO 1,000,000 AND AN ISOTACTIC CONTENT OF ABOUT 50 TO 98 WT. PERCENT, AND (2) FROM 1 TO 20 WT. PERCENT OF AN ETHYLENE/VINYL ACETATE COPOLYMER CONTAINING FROM ABOUT 10 TO 40 WT. PERCENT VINYL ACETATE HAVE IMPROVED TENSILE STRENGTH, HARDNESS, SOFTENING POINTS AND GLOSS, WITHOUT MARKEDLY INCREASED VISCOSITY OR SHRINKAGE, AND HAVE CLOUD POINTS NOT APPRECIABLY HIGHER THAN THAT OF THE PETROLEIUM WAX CONSTITUENT. THESE BLENDS ARE PARTICULARLY USEFUL AS OCATINGS FOR PAPER, PAPERBOARD AND THE LIKE.

Abstract: CRYSTALLINE 1,2 BUTADIENE POLYMER IS USED TOGETHER WITH A FREE-RADICAL CURING AGENT TO PRODUCED A MOLDING COMPOSITION. THE POLYBUTADIENE IS IN THE NORMALLY GRANULAR, CRYSTALLINE. LARGELY SYNDIOTACTIC FORM. WHEN MOLDING COMPOSITIONS OF THIS POLYBUTADIENE ARE FORMULATED ON A ROLL MILL, THE COMPOSITIONS ARE GRANULATED. THOSE FORMULATED WITH PEROXY CURING AGENT WILL READILY CURE TO A HEAT DISTORTION TEMPERATURE OF AT LEAST 250*C. EVEN WHEN CONTAINING AN ANTIOXIDANT SERVING TO INHIBIT PREMATURE CURING. CONVENTIONAL INGREDIENTS OF MOLDING COMPOUNDS SUCH AS FILLERS AND MOLD LUBRICANTS CAN BE INCORPORATED WITH THE COMPOSITIONS. THE COMPOSITIONS INCLUDING A PEROXY CURING AGENT AND AN ANTIOXIDANT CAN BE WORKED WITHOUT CURING AT TEMPERATURES ABOVE THE FUSION TEMPERATURE, AND CURED AT HIGHER TEMPERATURES.
