  • Publication number: 20130018121
    Abstract: Single-phase, liquid compositions, comprising at least two isocyanate-reactive polyol components that are incompatible with each other and, as a mediator additive, at least one copolymer that prevents or delays the separation of the polyol components and that is composed of certain structural units, of which certain structural units have no acidic functional groups and certain structural units have at least one acidic functional group and said structural units are optionally reacted at least partially with at least one preferably organic compound having at least one basic group to produce salt, and to the use thereof to produce polyurethanes or corresponding polyurethane items.

  • Publication number: 20120183787
    Abstract: A method of promoting the adhesion between a coating based on at least one polymer and a substrate surface that can be made of different materials in which an adhesion promoter comprising at least one, optionally oligomeric, addition product having no terminal C?C double bonds and has hydrolyzable silane groups and other functional groups is included in the coating composition, included in a preliminary coating applied to the substrate surface prior to the actual coating, is applied between the coating and substrate surface, or any combination thereof.

  • Patent number: 8153722
    Abstract: A curable polymer mixture comprising 1.) at least one at least oligomeric addition product a) of at least one amino silane and/or thiosilane having at least one hydrolysable silane group to at least one compound having at least two terminal, ethylenically unsaturated double bonds, and/or at least one at least oligomeric addition product b) of at least one isocyanate silane and/or epoxy silane having at least one hydrolysable silane group to at least one oligomeric compound having at least three recurring units and at least one terminal hydroxyl group or terminal amino group and at least one terminal ethylenically unsaturated double bond as coupling additive, 2.) a system which can be cured by radical polymerization, comprising at least one ethylenically unsaturated polymer and/or a (meth)acrylic resin, at least one ethylenically unsaturated monomer, at least one radical initiator and optionally at least one cross-linking agent as binder 3.

  • Patent number: 8129476
    Abstract: The present invention relates to modified comb copolymers comprising special structural units, which are produced by converting SMA resins and optionally special copolymers with an AB block copolymer structure with a mixture of at least one polyalkylene oxide monoamine and at least one amino alcohol, with a mixture of at least one polyalkylene oxide monoamine and at least one N,N-disubstituted diamine or a mixture of at least one polyalkylene oxide monoamine, at least one N,N-disubstituted diamine and at least one polymer selected from the group comprising monohydroxy-terminated polyalkylene oxides, monohydroxy-terminated polyesters and monohydroxy-terminated block copolymers comprising polyalkylene oxide and polyester blocks, and their monohydroxy-terminated side chains are converted to phosphoric acid ester groups or their N,N-disubstituted amino-terminated side chains are converted to quaternary ammonium salts, and their use as wetting and dispersing agents.
