Abstract (en)
[origin: WO2008145550A1] The invention relates to a composition comprising (A) 50 - 99.5 weight % of a reaction resin or a reaction resin mixture that can be processed into a thermosetting material and is liquid at temperatures in the range from 15 to 100°C and has an average molecular weight of 200 to 500,000, and having a sufficient number of suitable reactive groups for the curing process, and (B) 0.5 to 50 weight % of one or more three-dimensionally cross-linked redispersed polyorganosiloxane rubbers, which are homogenously present in the reaction resin or reaction resin mixture in a finely distributed form as polyorganosiloxane rubber particles having a diameter of 0.001 to 0.4 µm, the polyorganosiloxane rubber particles being made of a core (a) made of a silicone-organic polymer and an organopolymer shell (d) and optionally two inner shells (b) and (c), the inner shell (c) being an organic polymer and the inner shell (b) being a silicone-organic polymer, comprising (a) 20 to 95 weight %, relative to the total weight of the polyorganosiloxane rubber particle, of a core polymer of the general formula (R3SiO1/2)w(R2SiO2/2)x.(RSiO3/2)y.(SiO4/2)z, wherein w = 0 to 20 Mol %, x = 80 to 99.5 Mol%, y = 0.5 to 10 Mol%, z = 0 to 10 Mol%, (b) 0 to 40 weight %, relative to the total weight of the polyorganosiloxane rubber particle, of a polydialkylsiloxane shell made of units of the formula (R3SiO1/2)w(R2SiO2/2) x.(RSiO3/2) y.(SiO4/2)z, wherein w = 0 to 20 Mol %, x = 0 to 99.5 Mol%, y = 0.5 to 100 Mol%, z = 0 to 50 Mol%, (c) 0 to 40 weight %, relative to the total weight of the polyorganosiloxane rubber particle, of a shell made of organopolymer monoolefinically or polyolefinically unsaturated monomers, and (d) 5 to 95 weight %, relative to the total weight of the polyorganosiloxane rubber particle, of a shell made of organopolymer monoolefinically unsaturated monomers, wherein R means identical or different monovalent alkyl or alkenyl radicals having 1 to 6 carbon atoms, aryl radicals, or substituted hydrocarbon radicals.
