Abstract: Cationic thickener prepared by polymerizing a monomer composition comprising 15 to 85% by weight of at least one of acrylic monomer having an amino group and methacrylic monomer having an amino group, 20 to 80% by weight of vinyl monomer, 1 to 20% by weight of monomer having at least one of acryloyl group and methacryloyl group and 0.1 to 20% by weight of crosslinkable vinyl monomer, and a process for preparing the same. This cationic thickener contains little impurities, and can be easily mixed with a cationic polymer for setting, and forms a flexible film after drying.

Abstract: Cosmetic composition comprising cationic thickener prepared in a nonaqueous system in the absence of a surface active agent by polymerizing monomer composition containing 15 to 90% by weight of at least one of acrylic monomer having amino group and methacrylic monomer having amino group, 0 to 80% by weight of vinyl monomer, 1 to 60% by weight of monomer having at least one of acryloyl group and methacryloyl group and 0.1 to 25% by weight of crosslinkable vinyl monomer. This cosmetic composition imparts refreshing feeling and little skin irritation and can be suitably used as hair cream, hair lotion and the like.

Abstract: A coating composition comprising a colloidal silica, an organohydroxysilane, a partial condensate of the organohydroxysilane and a liquid medium containing ethylene glycol monobutyl ether in an amount of at least 20% by weight, which is applied to a substrate, shows excellent properties such as storage stability, workability for coating or painting, heat resistance, surface hardness, chemical resistance, abrasion resistance, scratch resistance, stain resistance and weather resistance.

Abstract: A process for preparing a 2,2,6,6-tetrahalocyclohexanimine derivative (I) which comprises reacting a 2,2,6,6-tetrahalocyclohexanone with a primary amine or ammonia in the presence of a Lewis acid, a process for preparing a 2,6-dihaloaniline derivative (II) which comprises subjecting the 2,2,6,6-tetrahalocyclohexaneimine derivative (I) to dehydrohalogenation in the presence or absence of a catalyst, and an N-phenyl-2,2,6,6-tetrahalocyclohexaneimine. According to the process of the present invention, the 2,2,6,6-tetrahalocyclohexaneimine derivative (I) can be prepared from inexpensive starting materials in high yield through a few steps. Also, the 2,6-dihaloaniline derivative (II) can be prepared from inexpensive starting materials in high yield and high purity through a few steps. Further, the N-phenyl-2,2,6,6-tetrahalocyclohexaneimine is very useful in the preparation of N-phenyl-2,6-dihaloaniline.

Abstract: A coating composition comprising a colloidal silica, a partial condensate of organoalkoxysilane hydrolyzate, a polymer or a copolymer of unsaturated ethylenic monomers, a surface active agent and glycol derivatives, which is coated on a wheel for vehicles shows excellent properties such as adhesive property, filiform corrosion resistance, stain resistance, weather-resistance and impact resistance. A wheel coated with the coating composition for vehicles also shows excellent properties such as filiform corrosion resistance, stain resistance, weather-resistance and impact resistance.

Abstract: This invention relates to a method for the purification of glycidyl acrylate or glycidyl methacrylate. Specifically, the invention effects the purification by using a residual catalyst-inactivating additive and consequently produces highly purified glycidyl acrylate or glycidyl methacrylate containing substantially no epichlorohydrin and having a low chlorine content.

Abstract: This invention provides a method for the manufacture of a high-expansion type absorbent polymer by first causing an absorbent polymer which is obtained by polymerization of a monomer and is possessed of an alkali salt of acrylic acid as a component of polymer to be cross-linked at the time of azeotropic dehydration thereof with a cross-linking agent possessing two or more functional groups in the presence of an inorganic salt and subsequently drying the cross-linked polymer. By the method of this invention, there can be obtained a high-expansion type absorbent material which absorbs water quickly and forms a gel not viscid but permeable to gas. This absorbent material is highly advantageously used as absorbent for sanitary materials free from leaking water and as a water-retaining agent for agricultural applications hardly causing rotton plant roots.

Abstract: Nitrides and carbides are prepared by intercalating a monomer, a starting material of condensate, or a prepolymer into the interlamellar spaces or the vacant spaces of the crystalline structure of a natural mineral or an inorganic compound to prepare an intercalated compound and baking the intercalated polymer compound at a temperature in the range of 1100.degree.-1700.degree. C. under a nitrogen or reducing atmosphere. The present invention provides a method for readily preparing nitrides and carbides having the increased crystallinity at a low calcination temperature. Whiskers with larger diameters of 2 to 5 .mu.m can be prepared by adding carbon powder to the intercalated compound complex.

Abstract: Disclosed is a vulcanization accelerator for chloroprene rubber which has a thioglycolic acid ester as its main component and which gives chloroprene products improved in physical properties, particularly tear strength. A modified vulcanization accelerator obtained by having an inorganic powder impregnated with, or adsorb, a thioglycolic acid ester constitutes a preferred embodiment in respect that it avoids emitting the offensive odor of mercaptan and permits easy handling.
