Abstract: A chlorosulfonated or chlorinated polyethylene dispersed in a polyolefin, vulcanized and then the vulcanizate dispersed into a thermoplastic chlorosulfonated or chlorinated polyethylene forming a partially crosslinked thermoplastic chlorosulfonated or chlorinated polyethylene vulcanizate having good interply adhesion, hot weld strength, commercial processability, and crack resistance.

Abstract: Thermoplastic vulcanizates are prepared by curing, at least partially by dynamic vulcanization, blends of chlorinated polyethylene and crystalline thermoplastic polymers such as polypropylene. Inclusion of a plasticizing material or extender oil, e.g. trioctyl trimellitate, enhances softness and oil resistance of the blends. Vulcanizing materials include a basic material, normally added with the chlorinated polyethylene, and (1) a derivative of 2,5-dimercapto-1,3,4-thiadiazole or (2) a combination of 2,5-dimercapto-1,3,4-thiadizaole and an activator material such as an amine having a boiling point of 110.degree. C. or higher and a pk value less than 4.5.

Abstract: An alumina support which contains cesium is prepared by adding a fusible compound of cesium to alumina along with known binders and porosity control agents. The cesium compound should be fusible below the temperature at which the alumina fuses. Such a support is especially useful as a support for a silver catalyst employed in the oxidation of ethylene to ethylene oxide.

Abstract: Alkylene glycols are produced from alkylene carbonates by hydrolysis in the presence of water at temperatures of from about 80.degree. to about 200.degree. C. Catalysts, such as alumina, are employed at temperatures from 80.degree. to about 150.degree. C. and only slightly greater than the stoichiometric amount of water is employed to allow the most efficient use of the process.

Abstract: An improved process for making ethylene carbonate wherein ethylene oxide and carbon dioxide are passed over an anion exchange resin catalyst and wherein the ethylene oxide and carbon dioxide reactants are absorbed from the effluent of an ethylene oxide reactor, desorbed and used as feed to the ethylene carbonate plant without further purification.

Abstract: In the manufacture of ethylene oxide by the partial oxidation of ethylene in the vapor phase, the effluent gases from the reaction are absorbed in water prior to separation and purification of the ethylene oxide. The present invention is the improvement in which ethylene carbonate is employed as the absorbing medium for the ethylene oxide.
