摘要： A water-dispersible hybrid polymer of a core/shell structure is provided which is based upon (A) a polymer (core) of a mercapto-functionalized poly(epoxyester) onto which (B) at least one addition polymer-based chain (shell) has been grafted via the addition polymerization of free-radically polymerizable monomers in the presence of the mercapto-functionalized poly(epoxyester). Also provided are aqueous dispersions of these hybrid polymers and coating compositions therefrom, which coating compositions are especially suited for use as clearcoats and surfacers.

摘要： The invention provides a stabilizer for an aqueous dispersion of an acrylic polymer that is obtained by successive copolymerization in random order of a monomer mixture A consisting of particular amounts of styrene or methyl styrene, acrylic acid or methacrylic acid, and optionally another comonomer, and a monomer mixture B consisting of particular amounts of styrene or methyl styrene, a (cyclo)alkyl methacrylate having 1-12 carbon atoms in the (cyclo)alkyl group, and optionally another comonomer, in the presence of a particular amount of a polybutadiene having a number average molecular weight of 1500-10000, the carboxylic acid groups from the (meth)acrylic groups being at least partly ionized. The invention also pertains to an aqueous dispersion of an acrylic polymer thus stabilized.

摘要： Stable dispersion of addition (co)polymers in an inert relatively non-polar organic hydrocarbon liquid, the dispersed particles embracing both a (co)polymer and a polymer containing an ethylenically unsaturated monomer. The (co)polymers are substantially composed of:(a) 5 to 100 mole % of styrene and/or methyl styrene;(b) 0 to 95 mole % of alkyl methacrylate having 1 or 2 carbon atoms in the alkyl group and/or alkoxyalkylene methacrylate having 1 or 2 carbon atoms in the alkoxy group and the alkylene group;(c) 0 to 40 mole % of alkyl methacrylate having 3 to 12 carbon atoms in the alkyl group;(d) 0 to 40 mole % of hydroxalkyl methacrylate having 2 to 12 carbon atoms in the alkyl group and/or glycidyl methacrylate; and(e) 0 to 20 mole % of m methacrylic acid.The (co)polymers are grafted to a polymer of a number average molecular weight of 2000 to 10.000, at least 60% by weight of which consists of butadiene, the weight percentage of the butadiene-containing polymer being 20 to 200% of that of the (co)polymer and the sum of this percentage and the percentage of styrene and/or methyl styrene in the copolymer being higher than or equal to 50.At room temperature the dispersions dry to form a smooth and very glossy film.
