    摘要: A process for the preparation of multiphase formulations of organosilicon compounds by (A) formation of a mixture containing organic compound(s) (1) containing at least two aliphatic double bonds and of the general formula R2(CR1═CH2)x,  (1) in which R1 are a hydrogen atom or an alkyl radical having 1 to 6 carbon atoms per radical, R2 is a divalent, trivalent or tetravalent hydrocarbon radical having 1 to 25 carbon atoms per radical; and x denotes 2, 3 or 4 corresponding to the valence of R2; and an organopolysiloxane (2) having on average more than one Si-bonded hydrogen atom per molecule; a catalyst (3) promoting the addition of Si-bonded hydrogen at an aliphatic double bond; an emulsifier (4); and an agent (5) immiscible with (1) and (2); and (B) emulsification of the mixture, with the proviso that the ratio of aliphatic double bond in organic compound (1) to Si-bonded hydrogen in the organopolysiloxane (2) in (A) is such that toluene-soluble siloxane copolymers are obtained.
