Abstract: The invention relates to polymerizable materials comprising two components, where component I comprises: (a) from 0.1 to 20% by weight of at least one vinyl ether, (b) from 10 to 89.9% by weight of at least one ethylenically unsaturated monomer which is not a vinyl ether, (c) from 0.001 to 5% by weight of at least one accelerator, (d) from 9.999 to 89.899% by weight of fillers, thixotropy assistants, retardants and other auxiliaries, and component II comprises: (e) from 0.1 to 20% by weight of at least one barbituric acid derivative and/or at least one malonylsulfamide which is able to initiate the free-radical polymerization, and (f) from 0 to 89.9% by weight of fillers, thixotropy assistants, retardants and other auxiliaries, (g) from 10 to 80% by weight of conventional plasticizers, and to the use thereof.

Abstract: The invention relates to compositions containing:

Abstract: The invention relates to urethane prepolymers, obtainable by reaction of:

Abstract: A plasticized composition comprising 40 to 82 percent cellulose nitrate, having nitrogen content of less than 12.6% relative to the weight of said cellulose nitrate, and 18 to 60 percent formylated polyurethane, said percent, both occurrences, being relative to the weight of the composition, is disclosed. The plasticized composition is suitable for use in preparing paints.

Abstract: The present invention relates to polyester acrylate/urethane dispersions based on polyester acrylate prepolymers containing hydroxyl groups, obtainable by polyaddition ofA. 40-90 wt. % of one or more polyester acrylate prepolymers containing hydroxyl groups and having an OH content of 40-120 mg of KOH/g andB. 0.1-20 wt. % of one or more mono- and/or difunctional compounds reactive towards isocyanate groups, which compounds contain groups which are cationic, artionic and/or have a dispersant action due to ether groups withC. 10-50 wt. % of one or more polyisocyanatesD. 0.0-30 wt. % of polyolstogether with a subsequent reaction withE. 0.1-10 wt. % of one or more di- and/or polyamines.

Abstract: Polyethers which contain recurring units of the formula I ##STR1## in which A is a divalent aryl or heteroaryl radical,X is O, S or NR,Z is a divalent aryl or heteroaryl radical or an alkynyl, azo or (CF.sub.2) group, andR is arylare synthesized. The polyethers can be used as thermoplastics for the production of injection-molded articles, extrudates, polymer blends and coatings and for the production of films and membranes from solution.
