    Abstract: A method for producing raised textures on a substrate by printing or coating with a composition containing a film-forming polymer binder, solvent and thermally-expandable polymer particles (I) etc. and then heating the coating, in which (I) comprises optionally colored, expandable polystyrene microspheres with a particle diameter (unexpanded) of 0.1-5 mm. An Independent claim is also included for printing compositions for textile printing and coating compositions for foam coating, containing 1-99.9 wt% of an aqueous dispersion of polymer binder, 0.1-99 wt% particles (I), 0-98.9 wt% additional water and 0-98.9 wt% additives such as foam suppressants, emulsifiers, thickeners, crosslinkers, pigments, pigment distributors, dispersants and fillers.

    Abstract: Process for the preparation of homopolymers or copolymers by homopolymerization or copolymerization of free-radically polymerizable water-soluble and/or water-dispersible monomers, optionally with further comonomers and optionally with at least one crosslinker, in an inverse emulsion polymerization in the presence of at least one redox initiator pair comprising an oxidizing agent and a reducing agent, where the reducing agent is 2-hydroxy-2-sulfinatoacetic acid and/or salt thereof; homopolymers or copolymers preparable by the process according to the invention, water-in-oil emulsions which comprise at least one homopolymer or copolymer according to the invention, solid compositions which comprise at least one homopolymer or copolymer according to the invention, the use of 2-hydroxy-2-sulfinatoacetic acid and/or salt thereof as reducing agent in a process for the preparation of homopolymers or copolymers; the use of the water-in-oil emulsion comprising at least one homopolymer or copolymer according to the invention for the thickening of aqueous solutions, and the use of 2-hydroxy-2-sulfinatoacetic acid and/or salt thereof as reducing component of a redox initiator pair comprising an oxidizing agent and a reducing agent for avoiding induction times during inverse emulsion polymerization.

    Abstract: A particulate polymer P having an average particle diameter d50 of from 0.1 to 50 mum is prepared by a process in which an emulsion E is prepared fromone or more monomers M, which are polymerizable by free radical polymerization to give the polymer P,water, andat least one protective colloid PCby the action of high shear forces, and the emulsion E is subjected to polymerization in a reactor with the use of a free radical polymerization initiator RI wherein, based on the emulsion E, not more than 75% by weight of the emulsion E (initially taken portion of E) are initially taken in the reactor at the beginning of the polymerization and at least 25% by weight of the emulsion E (feed portion of E) are not fed to the reactor until after the beginning of the polymerization.
