    Abstract: Mixtures which are curable by heating or irradiation with actinic light contain one or more cationically curable compounds, such as an epoxy, an olefinically unsaturated monomer, amino resin or phenolic resin, and as a cationically active curing catalyst one or more N-sulfonylamino-sulfonium salts of the formula such as N-p-toluenesulfonyl-N-methylaminodiphenylsulfonium hexafluorophosphate with or without quinones or peroxides are suitable, inter alia, for producing moldings, coatings, relief images and resist patterns.

    Abstract: Process for improvement of the elasticity of a colored polymer system, which is composed of a matrix and of discrete polymer particles distributed in accordance with a defined spatial lattice structure in the matrix, and which is obtained by filming of an emulsion polymer with core/shell structure, where the emulsion polymer is obtainable via polymerization of monomers in at least one first stage (monomers of the core) and subsequent polymerization of monomers in at least one further, second stage (monomers of the shell), which comprises using monomers whose glass transition temperature is below 0° C. as at least 5% by weight of the monomers of the core.

    Abstract: Preparation of graft copolymers of at least one graft base (A), which exhibits a glass transition temperature of less than 0[deg]C and obtained from: (a1) butadiene and/or at least one acrylic acid monomer, monomers (a2), which are copolymerizable with (a1), crosslinking monomers (a3) and polymerization auxiliary materials (a4); and at least one grafting layer (B) with a glass transition temperature of greater than 30[deg]C, comprises emulsion polymerization of (a1-a4) and followed by grafting (B), where (A) is least polymerized at 20[deg]C. Preparation of graft copolymers of at least one graft base (A), which exhibits a glass transition temperature of less than 0[deg]C, a particle size of 30-2000 nm and obtained from: (a1) 40-100 wt.% of butadiene and/or at least one acrylic acid monomer of formula (CH2=C(O)OR), in which the alcohol component (R) exhibits 1-20C atoms, 0-50 wt.% of monomers (a2), which are copolymerizable with (a1), 0-5 wt.% of crosslinking monomers (a3) and 0-5 wt.% of polymerization auxiliary materials (a4); and at least one grafting layer (B) with a glass transition temperature of greater than 30[deg]C, comprises emulsion polymerization of (a1-a4) and followed by grafting (B), where (A) is least polymerized at 20[deg]C. Independent claims are included for: (1) graft copolymer, obtained by the above process; (2) thermoplastic molding material, comprising 4-90 wt.% of graft copolymer, 10-96 wt.% of at least one polymer from thermoplastic polymers or copolymers of polystyrene acryl nitriles, 4'-(9-acridinylamino)-methanesulfon-m-anisidide (AMSA), polyvinyl chloride, polyamide, polyesters, polymethacrylic acid ester, polymers of aromatic vinylmonomers or copolymers of styrene and methyl styrene, polyolefins, polycarbonates, polyethers, polyepoxides, diagonally crosslinked polyurethane, phenolic plastics and polyimides, 0-50 wt.% of fiber and/or particle forming fillers and 0-10 wt.% of further additives; and (3) molded article, foam, semi-finished material and foils, made of thermoplastic molding material.
