Abstract
There is disclosed a modified reaction resin with a content of 50 to 98% by weight of a liquid reaction resin or reaction resin mixture processed into thermosetting plastic with a suitable reactive group of sufficient number for the hardening process and 2 to 50% by weight of one or more three-dimensional crosslinked polyorganosiloxane rubbers, which are held in the reaction resin matrix in finely divided state as polyorganosiloxane rubber particles with a diameter of from 0.01 to 50 micrometers, together with small quantities of other auxiliary materials. The rubber particles have reactive groups on their surfaces, which in turn in the presence of auxiliary media serving as reactive components can react chemically with the reaction resin. There is also disclosed a process for the production of the modified reaction resins and their use for the production of fracture and impact resistant, also definitively shaped thermosetting plastics, fiber-reinforced plastics, insulation materials and laminated plastic.
