    摘要: THE PYROLYSIS OF ALKYLALUMINUM COMPOUNDS IN A NONOXIDIZING, NON-HYDROLYZING ENVIRONMENT PRODUCES A CATALYTICALLY ACTIVE SOLID WHICH IS CHARACTERIZED BY THE EVOLUTION OF A HYDROCARBON GAS UPON HYDROLYSIS. PREFERABLY, AN ALKYLALUMINUM COMPOUND IS HEATED AT TEMPERATURES IN EXCESS OF 400*F. FOR A TIME IN EXCESS OF 6 HOURS. THE CATALYST CAN BE UTILIZED TO PROMOTE VARIOUS CHEMICAL REACTIONS SUCH AS ALKYLATION, POLYMERIZATION, PARTICULARLY EPOXIDE POLYMERIZATION, ISOMERIZATION, DEHYDROGENATION, HYDROGENATION, CONDENSATION, DEALKYLATION, ARYLATION, ACYLATION AND DISPROPORTIONATION. VARIOUS IMPROVEMENTS ARE ALSO OBTAINED WHEN THIS CATALYST IS COMBINED WITH EITHER A LEWIS BASE, ALUMINUM CHELATE OR WATER.

    摘要: THIS INVENTION RELATES TO WAX COMPOSITIONS AND TO A METHOD FOR PRODUCING A SUITABLE DISPERSION IN WAX OF INSOLUBLE POLYMER OF THE VINYL AND VINYLIDENE SERIES WHICH COMPRISES POLYMERIZING THE MONOMERS IN SITU IN MOLTEN WAX IN THE PRESENCE OF A WAX-SOLUBLE POLYMER HAVING A MOLECULAR WEIGHT OF AT LEAST 8,000. PREFERABLY, THE WAXINSOLUBLE POLYMER IS A BUTADIENE-STYRENE COPOLYMER HAVING FROM 50-85 WEIGHT PERCENT BOUND STYRENE AND THE WAX-SOLUBLE POLYMER IS AN ETHYLENE/VINYLACETATE COPOLYMER HAVING FROM 5-50 WEIGHT PERCENT BOUND VINYL ACETATE. THE INSOLUBLE POLYMER MAY BE INCORPORATED INTO THE WAX IN AMOUNTS RANGING FROM 5-400 PARTS PER 100 PARTS OF WAX.

    摘要: Soluble solid easily handled polyepoxide polymers can be formed from 4-vinylcyclohexene diepoxide in a catalytic process using a tertiary amine and an active hydrogen containing compound. The powdery polymers of the invention can be easily cured to thermoset resins using coreagents to form castings, laminates, and coatings having exceptional toughness and good strength.
