ABSTRACT:
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) 30 to 60% by weight of a polyacrylic ester having 4 to 10 acryloyloxy groups, (B) 20 to 70% 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.
