Abstract:
1. A composition comprising (A) 50-99.5% by weight based on the total weight of A, B and C of a reactive resin or reactive resin mixture which can be processed to give thermosets, and which is liquid at temperatures in the range from 15 to 100° C. and has an average molecular weight of from 200 to 500,000, and has a sufficient number of suitable reactive groups for the curing process, and (B) 0.5-50% by weight based on the total weight of A, B and C of one or more dispersed polyorganosiloxanes, which are present homogeneously in finely dispersed form as polyorganosiloxane droplets having a diameter of from 0.001 to 4 μm in the reactive resin or reactive resin mixture, wherein the polyorganosiloxane droplets are a polymer of the general formula (R (C) 0.1-50% by weight based on the total weight of A, B and C of one or more siloxane-containing block copolymers as dispersants, which form a homogeneous solution or emulsion in the reactive resin or reactive resin mixture.
