    Abstract: Process for preparing polymers comprising S-vinylthioalkanol as monomer by radical polymerization, the polymerization being carried out in aqueous solution, with the proviso that no N-vinylpyrrolidone as monomer is used for preparing the polymers, and also polymers prepared by such processes. Copolymer consisting of S-vinyl-2-thioethan-1-ol and one or more ethylenically unsaturated monomers selected from the group consisting of acrylic acid, itaconic acid, maleic acid, maleic anhydride, and vinylphosphonic acid. Mixtures, preferably aqueous compositions, comprising polymers or copolymers. Use of polymers, copolymers, or aqueous compositions as concrete plasticizers, wetting agents, in cosmetics, as adhesive constituent, in emulsion polymerization, for metal surface treatment, in coatings applications, in paints, in laundry detergents, in washing detergents, as encapsulating material or as enveloping material.

    Abstract: A curable composition comprises a) at least one epoxide compound E having at least two epoxide groups; b) at least one amine A having at least two amine hydrogens; and c) at least one acrylic ester U; wherein the epoxide compound E comprises at least one epoxide compound E′, the amine A comprises at least one amine A′, and the acrylic ester U comprises at least one acrylic ester U′ whose Hansen solubility parameters for the dipole forces δp and for the specific interactions δh satisfy the following conditions: ( δ p ⁡ ( U ′ ) - δ p ⁡ ( E ′ ) ) 2 + ( δ h ⁡ ( U ′ ) - δ h ⁡ ( E ′ ) ) 2 ≥ 1.5 ⁢ ⁢ and ( δ p ⁡ ( U ′ ) 2 + δ h ⁡ ( U ′ ) 2 ) - ( δ p ⁡ ( A ′ ) 2 + δ h ⁡ ( A ′ ) 2 ) ≥ 0 . A suitable choice of the Hansen solubility parameters of the constituents ensures that the acrylic ester is incorporated covalently into the curing material, preventing subsequent evaporation of the diluent.
