    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 method for producing a tridimensional structure comprises: (a) ejecting an object material through a first print head; (b) ejecting a first pre-supporting material through a second print head; (b′) ejecting a second pre-supporting material through a third print head, the pre-supporting materials comprising liquid components which form a solid supporting material when brought together; (c) radiation curing the object material; steps (a) to (c) are repeated several times in order to form the tridimensional structure layer by layer, and the object material and the supporting material comprise at least one common boundary surface; and (d) removing the cured supporting material by treatment with an aqueous medium. The supporting material is suitable for supporting overhanging components and structures located above hollow spaces. The use of a supporting material cured by a different mechanism than the object material prevents undesirable interactions between the object material and the supporting material during curing.
