Abstract: 1. Aqueous solution or dispersion of a hydrolyzed copolymer of styrene and maleic anhydride having a molar ratio of styrene to maleic anhydride superior to 1 : 1 and a molecular weight (numerical average) of more than 400, characterized in that the copolymer has a molar ratio in the range of from 1.5 : 1 to 6 : 1 and a molecular weight of from 500 to 80 000, 1 to 60 percent of the carboxyl groups of the copolymer are neutralized, and the pH of the solution or dispersion is below 7.

Abstract: 1,223,477. Curing epoxy resins. FARBWERKE HOECHST A.G. 15 Aug., 1968 [23 Aug., 1967], No. 39144/68. Heading C3B. [Also in Division B2] Epoxy resins are cured using a mixture of: (I) a Lewis acid and (II) a phosphorus compound in which R and R 1 are each C 1-10 alkyl, aryl, cycloalkyl, alkaryl, aralkyl, alkoxyalkyl, alkoxyaryl, hydroxyalkyl, hydroxyaryl, hydroxyaralkyl or alkenyl radicals which may optionally be substituted by halogen, e.g. Cl or Br. Examples of I are: BF 3 or its complexes with amines or ethers, SnCl 4 , SbF 5 , SbCl 5 , or PCl 5 . Examples of II are: vinyl-, methyl-, ethyl-, 2-chloroethyl-, 1,2 - dichloroethyl, propyl, butyl, hydroxymethyl-, 1 - hydroxyethyl, 2 - hydroxypropyl or α - hydroxybenzyl - phosphonic acid or methyl-, ethyl-, propyl-, isopropyl-, n-butyl-, iso-butyl-, tert - butyl-, methoxymethyl-, butoxyethyl-, phenyl-, 2 - methylphenyl-, 3 - methylphenyl or 2,4,6 - trichlorophenyl - monoesters of phosphoric acid. I may be used at 0À1 to 5 mole per cent per average epoxide equivalent of the resin. II may be used so as to provide 0À2 to 0À6 hydroxyl equivalents per epoxide equivalent of the resin. Conventional fillers, pigments and dyestuffs may be present. Curing may take place at ambient temperature.

Abstract: Emulsifier-containing plastics dispersions which serve as a binder for dispersion paints, should contain polymers forming a film at room temperature and having a high wet adhesion. Suitable polymers are prepared by polymerization of olefinically unsaturated monomers initiated by free radical-forming agents, especially in the presence of an emulsifier. As emulsifier there is used a salt of an acyl ester of the hydroxymethane-phosphonic acid. The emulsifier may remain in the dispersion ready-for-use without involving disadvantages for the wet adhesion.
