摘要:
THE PYROLYSIS OF ALKYLALUMINUM COMPOUNDS IN A NONOXIDIZING, NON-HYDROLYZING ENVIRONMENT PRODUCES A HYDROCARBON INSOLUBLE, OXIDIZABLE SOLID WHICH IS CHARACTERIZED BY THE EVOLUTION OF A HYDROCARBON GAS UPON HYDROLYSIS. PREFERABLY, AN ALKYLALUMINUM COMPOUND IS HEATED AT A TEMPERATURE IN EXCESS OF 400*F FOR A TIME IN EXCESS OF 6 HOURS. THIS PYROLATE CAN THEN BE COMBINED WITH A REDUCIBLE TRANSITION METAL COMPOUND TO PROVIDE A CATALYST FOR THE POLYMERIZATION OF ALPHA OLEFINS.
摘要:
Method of road surface stabilization particularly suitable for roads in the Arctic and sub-Arctic regions by admixing the surface aggregate of the road with an aqueous bituminous emulsion wherein the dispersed phase is a bituminous composition containing an elastomeric polymer produced in situ and chemically bound to the bituminous composition thereby providing excellent low temperature properties to the road surface stabilizing composition.
摘要:
Novel compositions of matter comprising polymers of adamantyl epoxides and adamantyl epoxides useful as intermediates in the preparation of said polymers. The polymers are useful in making wax additives, gaskets and rubber-like compositions. A process for the preparation of adamantyl epoxides comprising contacting an alkenyl adamantane with an oxidizing agent selected from the group consisting of organic peracids and their derivatives, inorganic peracids, halogenhydrins and their derivatives, hydrogen peroxide, and organic hydroperoxides.
