Abstract: The invention relates to polymerizates that can be obtained by a) reacting at least one polyisocyanate with at least one polyol and optionally at least one radically curable monomer A with groups reactive toward isocyanate in at least one radically curable monomer B to form polyurethane particles having an average diameter of less than 40 nm, preferably less than 20 nm, and especially preferably less than 10 nm and an average number of radically curable functionalities in a range of 2 to 4, preferably 2 to 3, and b) emulsion polymerizing the product obtained under a). By means of the emulsion polymerization, larger cross-linked polyurethane/polymer hybrid dispersions are produced, in which the nanoparticles act as a connecting member between the polymer areas and the polyurethane components.

Abstract: The invention relates to a non-aqueous dispersion of organic polymer particles in a reactive diluent. Said non-aqueous dispersion can be obtained in that at least one monomer is polymerized in the reactive diluent, forming the organic polymer particles, wherein the reactive diluent does not participate in said polymerization due to the orthogonal reactivity thereof relative to the monomers, but comprises a functionality allowing later targeted polymerization. Depending on the organic polymer particles or reactive diluents used, the non-aqueous dispersion can be used in multifaceted applications having a wide range of application profiles. In order to produce said non-aqueous dispersion, polymerization of at least one monomer in a stirred tank reactor in the presence of a reactive diluent is particularly suitable, wherein the conversion is performed at a stirring speed of at least 2 m/s, wherein the ratio of the stirrer diameter to the vessel diameter is set to 0.3-0.

Abstract: Disclosed are anhydrous transparent dispersions of polyurethane(meth)acrylate particles in a reactive diluent, which can be obtained by reacting a polyisocyanate with at least one polyol and a nucleophilically functionalized (meth)acrylic acid ester in the reactive diluent. The inventive dispersions are characterized in that the polyurethane(meth)acrylate particles have an average diamert of less than 40 nm. The invention further relates to a method for producing such dispersions, the use thereof as an adhesive, cut glass, or impact resistance modifier, and a molded article made from said dispersion.

Abstract: A silane-containing methacrylate resin composition which produces non-yellowing polymers. The composition contains 20-99.9% by weight (meth)acrylic acid ester, optionally other comonomers or polymers and softeners as well as 0.1-30% by weight of a silane. 100 parts by weight of this mixture are polymerized in the presence of a free radical initiator, Cu.sup.2+ and a quaternary amine. The components can be stored in premixtures and brought to reaction. The polymer can be used in glass laminates.
