Inherently highly abrasion-resistant cast articles are prepared by polymerizing a composition comprising (I) as a first component from 0 to 100 parts of urethane polyacrylic ester and (II) as a second component, correspondingly from 100 to 0 parts of a composition containing (A) 45 to 60% by weight of a polyacrylic ester having 4 to 10 acryloyloxy groups, (B) 20 to 55% by weight of a polymerization shrinkage modifier, and (C) 0 to 30% of a diluent monomer. A source of free-radicals may be added to the composition.
固有高耐磨铸件是通过聚合一种组合物来制备的,该组合物包括:(I) 作为第一组分的 0 至 100 份聚氨酯聚丙烯酸酯;(II) 作为第二组分的 100 至 0 份组合物,该组合物相应地含有:(A) 45 至 60% (按重量计)具有 4 至 10 个丙烯酰氧基的聚丙烯酸酯;(B) 20 至 55% (按重量计)聚合收缩改性剂;(C) 0 至 30% 稀释剂单体。组合物中可加入自由基源。
