    摘要： A composition for making vulcanized butadiene rubber, wherein the amounts of sulfur as a vulcanizing agent and of zinc oxide as a vulcanizing activator are greatly reduced as compared with the conventional rubber compositions. By vulcanizing such a rubber composition, there can be produced vulcanized butadiene rubber having high tear strength, tensile strength and resistance to aging which have been unable to be realized by the conventional butadiene rubbers.

    摘要： The present invention relates to a polyvinyl chloride resin composition prepared by mixing polyvinyl chloride resin with a graft polymer which is produced by grafting methyl methacrylate, styrene and acrylonitrile to a styrene-butadiene copolymer. More particularly, the present invention relates to a polyvinyl chloride resin composition prepared by mixing polyvinyl chloride resin with a graft polymer and, in the preparation of the latter from styrene-butadiene copolymer methyl methacrylate, styrene and acrylonitrile, the styrene-butadiene copolymer latex is first treated by heating and agitating under a specified condition at least in the presence of a certain amount of methyl methacrylate, and then the remainder of methyl methacrylate, styrene and, acrylonitrile is added in the presence of polymerization initiator until the polymerization reaction is completed. The polyvinyl chloride resin composition can provide molded matters having excellent impact resistance and superior transparency in a wide range of molding conditions, for example, by the blow molding process.

    摘要： Crystalline polyethylenimine or hydrate thereof is prepared by hydrolyzing poly(N-formyl ethylenimine) at a temperature of 20* 130*C. in the presence of an inorganic base. The crystalline polyethylenimine or its hydrate of this invention is in the state of solid or powder, and is insoluble in water at room temperature but soluble in hot water. This crystalline polyethylenimine and its hydrate may be useful as the water treating agent, paper sizing auxiliary agent, and trapping agents for heavy metals or polar compounds, etc.
