  The disclosure relates to a self-reinforcing semifinished product capable of thermoplastic shaping, composed of a single-layer sheet made from filled poly(meth)acrylate, where the semifinished sheet product has an average filler content F m in per cent by weight, based on its total weight, an upper side U and a lower side L, characterized in that the upper side U of the semifinished sheet product has been depleted with respect to fillers and the lower side L has been enriched with respect to fillers, in each case in relation to F m . A process for producing the semifinished products is also claimed. The semifinished poly(meth)acrylate sheet products of the invention are used in particular for producing sanitary items, such as shower trays and washbasins, preferably by a high-performance shaping process, such as thermoforming.

  本公开涉及一种可热塑成型的自增强半成品，由填充聚（甲基）丙烯酸酯制成的单层片材组成，其中半成品片材的平均填充物含量 F m 以总重量为基准，以重量百分比为单位，有一个上侧 U 和一个下侧 L，其特征在于，半成品板材的上侧 U 已减少了填料，而下侧 L 则增加了填料，在每种情况下，相对于 F m . 本发明还要求一种生产半成品的工艺。 本发明的聚(甲基)丙烯酸酯片状半成品特别用于生产卫生用品，如淋浴盘和洗脸盆，最好采用高性能成型工艺，如热成型。

  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 diameter of less than 40 nm. The invention further relates to a method for producing such dispersions, the use thereof as an adhesive, cast glass, or impact resistance modifier, and a molded article made from said dispersion.

  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. This structure results in improved chemical resistance and significantly improved mechanical properties in comparison with traditional polyurethane dispersions, in which polyurethane nanoparticles are subsequently dispersed in polyacrylates, for example by means of an acetone method. Furthermore, the content of polyurethane in the polymer can be better controlled by means of this production method. The invention further relates to a method for producing such polymerizates and the use of such polymerizates as adhesives or coatings, in particular for textiles, or as paints, or for films and foils.
