    Abstract: Silicon-containing polymers consist of a) from 65 to 99.95 parts by weight of one or more acrylates and/or methacrylates of an aliphatic alcohol of 1 to 12 carbon atoms (monomers A), b) from 0 to 30 parts by weight of one or more ethylenically unsaturated monomers capable of undergoing free radical copolymerization (monomers B), c) from 0.05 to 10 parts by weight of one or more anhydrides of an alpha , beta -monoethylenically unsaturated dicarboxylic acid of 4 to 10 carbon atoms (monomers C) or from 0.1 to 10 parts by weight of one or more monomers containing one or more isocyanate groups and capable of undergoing free radical copolymerization (monomers D) and d) effective amounts of one or more silanes of the general formula I NH2-R1-Si(R2)3-m(R3)m(I) where m is 0, 1 or 2, R1 is a hydrocarbon chain of not more than 10 carbon atoms which may be interrupted by oxygen or nitrogen, the radicals R2 are identical or different hydrolyzable groups and the radicals R3 are identical or different C1-C5-alkyl groups. These silicon-containing polymers are suitable as base polymers for the preparation of sealing compounds curable under the action of atmospheric humidity.

    Abstract: Aqueous dispersions containing a polyurethane and from 5 to 60% by weight, based on the polyurethane, of an adhesion-improving polymer, the polyurethane consisting essentially of (a) organic diisocyanates, (b) dihydroxy compounds which have a molecular weight of from more than 500 to 5,000 g/mol and contain no ionic groups or groups convertible into ionic groups, (c) compounds having one or two functional groups reactive toward isocyanate and at least one ionic group or group convertible into an ionic group and (d) compounds having at last 3 isocyante groups or at least 3 functional groups reactive toward isocyanate, (e) optionally compounds which differ from (c) and have two functional groups reactive toward isocyanate and a molecular weight of from 60 to 500 g/mol, the compounds (d) being used in amounts such that the functionality F of all components is from 2.01 to 2.5, and the polyurethane or a prepolymer thereof is prepared in a water-miscible solvent boiling below 100 DEG C. and, after addition of the adhesion-improving polymer, is dispersed in water.

    Abstract: The invention relates to copolymers built up from A) from 99.5 to 75 % of olefinically unsaturated monomers containing hetero atoms, B) from 0.5 to 25 % of unsaturated compounds of the formula I and C) from 0 to 20 % of further olefinically unsaturated monomers where X is O, S or NR and R is optionally substituted C2-C6-alkylene, and R is C1- to C8-alkyl or phenyl. The products according to the invention are suitable as coating and impregnation compositions and in particular as contact adhesives.
