Casting resins based on acrylic acid esters

Abstract From the Canadian patent

The present invention is concerned with casting resins made from acrylic acid esters, with a high content of finely dispersed fillers. According to the invention the casting resins contain a mixture of organo-silicon compounds with functional groups and metal acid esters of metals of Sub-groups IV and V of the Periodic System of the Elements. The functional group of the organo-silicon compound is ethylenically unsaturated and connected with the silicon atom either directly or through alkylene groups. The addition of this mixture to the casting resin known per se achieves a lowering of viscosity of these resins which are employed chiefly for the production of sanitary articles.
