    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: 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: The invention relates to a process for the preparation of radiation-crosslinkable contact adhesive mixtures comprising polymers having a glass transition temperature of below 0 DEG C and a K value of from 20 to 80, derivatives of dihydroxypropyl (meth)acrylates as reactive thinners and small amounts of polymerisable tertiary amino compounds, in which the mixture is heated at temperatures of from 80 to 120 DEG C for up to 2 hours, and the solvent is then removed, if necessary at reduced pressure.

    Abstract: The novel copolymers having K values of from 5 to 80 are prepared by free-radical polymerisation of A) 20 to 80% by weight, based on the total weight of (A) and (B), of at least one olefinically unsaturated polyoxyalkylene alcohol or polyester alcohol adduct, (B) 80 to 20% by weight, based on the total weight of (A) and (B), of at least one vinyl monomer from the group comprising N-vinylformamide, -2-pyrrolidone, -2-piperidone, -2-caprolactam, -imidazole, -2-ethyleneurea and -2-propyleneurea, C) 0.05 to 40 parts by weight of glycidyl acrylate and/or glycidyl methacrylate, D) 0 to 10 parts by weight of at least one alpha , beta -monoolefinically unsaturated acid and E) 0 to 30 parts by weight of at least one olefinically unsaturated carboxamide and/or carboxylate and/or styrene, the parts by weight of (C), (D) and (E) in each case being based on 100 parts by weight of the monomers (A) and (B). The copolymers are used as assistants and/or additives, for example as dispersion and/or emulsification assistants, or as additives for improving the mechanical properties, in formulations for the preparation of polyisocyanate polyaddition products.
