    Abstract: Disclosed are casting resins made from acrylic acid esters with a high content of finely dispersed fillers. The casting resins contain a polymeric organosilicon compound having functional and nonfunctional groups. As functional groups, the copolymer contains one or more alkoxysilyl groups and one or more (meth)acryloxysilyl groups. The copolymer furthermore contains by copolymerization at least one nonfunctional comonomer having an ethylenically unsaturated grouping as well as an additional comonomer of the group of the vinyl carboxylic acid esters and (meth)acrylic acid esters, if desired. The addition of these polymeric organosilanes to known casting resins brings about a greater lowering of the viscosity of these resins, which are used, for example, for the manufacture of sanitary appliances.

    Abstract translation: 公开了由具有高含量的细分散填料的丙烯酸酯制成的浇铸树脂。 铸塑树脂含有具有官能团和非官能团的聚合物有机硅化合物。 作为官能团，共聚物含有一个或多个烷氧基甲硅烷基和一个或多个（甲基）丙烯酰氧基甲硅烷基。 共聚物进一步含有至少一种具有烯属不饱和基团的非官能共聚单体以及乙烯基羧酸酯和（甲基）丙烯酸酯基团的另外的共聚单体，如果需要的话。 将这些聚合物有机硅烷加入到已知的铸塑树脂中导致这些树脂的粘度的更大降低，例如用于卫生设备的制造。
