Abstract: A method of reducing allergenicity of latex rubber products such as latex rubber gloves. The latex rubber product is treated with first bath of an alkane hydrocarbon followed by a protein substituting material in the form of a synthetic plasticizer. A final wash is carried out using an alkaline or oxidative wash to remove surface and interstice dwelling protein.

Abstract: A curable organopolysiloxane composition is disclosed, comprising (A) 100 parts by weight of an organopolysiloxane having at least two monovalent aliphatic unsaturated hydrocarbon groups bonded to the silicon atoms per molecule, (B) an organopolyhydrogensiloxane having at least three hydrogen atoms bonded to the silicon atoms per molecule in such an amount that the number of the hydrogen atoms bonded to the silicon atoms falls within a range of from 0.25 to 8 per monovalent aliphatic unsaturated hydrocarbon group in component (A), (C) a catalyst selected from the group consisting of platinum and platinum compounds in an amount of from 0.

Abstract: The invention provides novel macromonomer and carboxyl functional polyurethanes having a high carboxyl content. The invention further provides dispersions, coatings and magnetic recording media comprising these polyurethanes, or blends or copolymers of these polyurethanes with quaternary ammonium compounds. The invention further provides novel dispersions, coatings and magnetic recording media comprising combinations of carboxyl functional polyurethanes having a high carboxyl content with quaternary ammonium polymers.

Abstract: A fibrillar copolyester having excellent heat resistance, a reinforcing effect and a large aspect ratio is produced with high dimensional stability and efficiency. A specific fibrillar copolyester having an aspect ratio of at least 3.0 is produced by polymerizing with shearing specific hydroxy aromatic carboxylic acid monomers as starting materials in a nonpolar solvent having 10 or more carbon atoms. Such hydroxy aromatic carboxylic acid monomers preferably have acetylated hydroxyl groups when copolymerized. Additionally, substituents other than hydrogen atoms optionally may be present on the rings of the aromatic monomers when forming the fibrillar copolyester.

Abstract: A composition for surface treatment, which comprises the following components (I), (II) and (III) as essential components:(I) at least one compound capable of forming a coating film with a contact angle of at least 70.degree. against water;(II) a solvent capable of dissolving the component (I); and(III) a solvent having an evaporation rate lower than the component (II).

Abstract: The curable organosiloxane compositions of the present invention contain a hydrosilylation catalyst that is microencapsulated within a layer of silicone resin or polysilane resin. These compositions are characterized by the presence of carbon black or a member from a specified group of metal compounds that prevents coagulation in cured materials of the resin portion of the microencapsulated catalyst.

Abstract: A water repellency treatment agent which is non-corrosive to metals, comprising a solution as a volatile solvent of 1-20 wt % of silyl phosphate containing 1-10 wt % of phosphorus, and less than 20 wt % of an organopolysiloxane of general formula R.sub.a SiO.sub.(4-a)/2 having a viscosity of 5-10,000 centistokes at 25.degree. C., wherein the letter a has a value in the range 1.95<a<2.20, and R is a monovalent organic group selected from saturated or unsaturated monovalent hydrocarbon groups with 1-30 carbon atoms, halogenated hydrocarbon groups, alkoxy groups, hydroxyl groups and hydrogen atoms.

Abstract: Described herein are compositions comprising the reaction product of a polyol, a multi-functional isocyanate, a lactone-acrylate adduct and an hydroxyalkyl acrylate. These compositions are suitable for use as curable coatings.

Abstract: Novel polyamide-imide resin compositions, useful for electrically insulating conductors, are prepared by polycondensing a tribasic acid anhydride compound and a diisocyanate in an inert organic solvent in the presence of a catalytic amount of an oxyanion or amine compound at a high solids content, and controlling the reaction to prevent a great increase in viscosity.
