    Abstract: Compositions which can be crosslinked under an atmospheric oxygen atmosphere by means of ultraviolet irradiation and are based on (meth)acrylate copolymers having a K value of from 10 to 100, obtained by free-radical polymerisation in solid phase or solution of a) 5 to 97.4% by weight of i-amyl acrylate and/or i-amyl methacrylate and b) 0 to 89.9% by weight of (meth)acrylates whose hompolymers have a glass transition temperature of below -30 DEG C, c) 2.5 to 30% by weight of alpha , beta -monoolefinically unsaturated compounds whose homopolymers have a glass transition temperature of above - 30 DEG C, d) 0 to 10% by weight of monoolefinically unsaturated acids and/or anhydrides thereof, e) 0 to 20% by weight of further olefinically unsaturated monomers containing at least one of the following functional groups: hydroxyl, amide, epoxide, ether, ester, urethane, urea, primary, secondary or tertiary amine and ether, and f) 0.1 to 5% by weight of a copolymerisable benzophenone or acetophenone derivative, the sum of the percentages by weight x = a + b + c + d + f in each case being 100.

    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.
