    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.

    Abstract: O.Z. 0050/40301 Materials which are crosslinkable by ultraviolet radiation under atmospheric oxygen and are based on (meth)acrylate copolymers having a X value of from 10 to 100 are obtained by free radical polymerization, in the presence or absence of a solvent, of a) from 5 to 97.4% by weight of isoamyl acrylate and/or isoamyl methacrylate, b) from 0 to 89.9% by weight of (meth)acrylates whose homopolymers have a glass transition temperature below -30.degree.C, c) from 2.5 to 30% by weight of .alpha.,.beta.-monoolefinically unsaturated compounds whose homopolymers have a glass transition temperature above -30.degree.C, d) from 0 to 10% by weight of monoolefinically unsaturated acids and/or their anhydrides and e) from 0 to 20% by weight of further olefinically unsaturated monomers having one or more of the following functional groups: hydroxyl, amide, epoxide, ether, ester, urethane, urea, primary, secondary and tertiary amine and ether groups, and f) from 0.1 to 5% by weight of a copolymerizable benzophenone derivative or acetophenone derivative, the sum of the percentages by weight X (= a + b + c + d + f) being 100 in each case.

    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: Paper and paperboard of high dry strength are produced by adding a dry strength enhancer to the paper stock and dewatering the paper stock with sheet formation by using as the dry strength enhancer a mixture of a cationic polymer which contains as characteristic monomers copolymerized units of (a) diallyldimethylammonium chloride, (b) N-vinylamine or (c) a substituted or unsubstituted N-vinylimidazoline and has a K value of not less than 30, and natural potato starch which is converted into a water-soluble form by heating in an aqueous medium at above the gelatinization temperature of natural potato starch in the absence of any oxidizing agents or alkali.
