摘要： A novel composite high-nitrile fiber in which the polymers are arranged in a sheath core type configuration. One polymer of the composite filament comprises a solventless, waterless, melt-processable acrylonitrile olefinically unsaturated polymer and the other polymer of the composite filament comprises an organic polymer. Either polymer can be employed as the sheath or the core component of the composite filament.

摘要： A protective coating which is resistant to attack by basic solutions is formed from interpolymers containing maleic anhydride (MAH). An article is coated with a solution of the dissolved ammonium or amine salts of the MAH interpolymer, or if the article itself contains MAH the salts may alternatively be formed on the surface of the article by applying a basic solution containing the ammonium or amine ions. The article is then dried and heated at a temperature sufficient to form the cyclic imide structure from the ammonium or amine salt of the MAH, typically about 160 to 200.degree. C.

摘要： A plasticized resin system is described, and the system comprises an intimate mixture of(a) an interpolymer derived from at least one vinyl monomer and an .alpha.,.beta.- unsaturated dicarboxylic acid, anhydride or the lower alkyl esters thereof, and(b) a plasticizing amount of a hydroxy substituted fatty acid containing at least about eight carbon atoms.The plasticized resin system also may contain at least one additional polar resin such as polycarbonates, polysulfones, polyesters, etc. The use of the hydroxy substituted fatty acid in this manner improves the processability of the interpolymers.
