    Abstract: Aqueous polymer dispersions comprising an emulsion polymer, an acid polymer comprising at least 5 wt.% ethylenically unsaturated monocarboxylic acids, dicarboxylic acids or dicarboxylic acid anhydrides and an alkoxysilane are prepared by emulsion polymerization in the presence of at least a portion of the alkoxysilane. Aqueous polymer dispersions (I) comprising an emulsion polymer, an acid polymer comprising at least 5 wt.% ethylenically unsaturated monocarboxylic acids, dicarboxylic acids or dicarboxylic acid anhydrides and an alkoxysilane of formula SiR R R R (I) are prepared by emulsion polymerization in the presence of at least a portion of the alkoxysilane: R -R = an organic group of which at least one is an alkoxy group.

    Abstract: A thermally curable, aqueous composition comprises at least a carboxyl group containing copolymer, a higher functional beta -hydroxyalkylamine and optionally a surfactant. A thermally curable, aqueous composition (I) comprises: (A) at least a carboxyl group containing copolymer prepared from 50-99.5 wt.% of an ethylenically unsaturated mono- and/or dicarboxylic acid, 0.5-50 wt.% of an ethylenically unsaturated compound, preferably an ethylenically unsaturated monocarboxylic acid ester or half esters or diesters of ethylenically unsaturated dicarboxylic acids with at least a hydroxyl group containing amine and up to 20 wt.% of other monomers; (B) at least a higher functional beta -hydroxyalkylamine; and (C) optionally a surfactant. Independent claims are included for the following: (i) the carboxyl group containing copolymer; (ii) a process for the production of the composition (I) by reaction of an ethylenically unsaturated mono- and/or dicarboxylic acid or corresponding derivative with a hydroxyl group containing amine and reaction of the resulting ester product with an ethylenically unsaturated mono- and/or dicarboxylic acid and/or their anhydrides and optionally other monomers to form a carboxyl group containing copolymer with reaction of the copolymer with a higher function beta -hydroxylalkylamine and optionally a surfactant and other additives; and (iii) a bonded substrate prepared by treatment with the composition (I) followed by curing.
