Abstract:
A process for the preparation of multiphase formulations of organosilicon compounds, said process comprising:(A) supplying a mixture containing an organic compound (1) containing at least two aliphatic double bonds having the general formula R2(CR1&boxH;CH2)x,â€ƒâ€ƒ(1) â€ƒin 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) which promotes 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) emulsifying the mixture, with the proviso that the ratio of aliphatic double bonds in organic compound(s) (1) to Si-bonded hydrogen in the organopolysiloxane(s) (2) is such that toluene-soluble siloxane copolymers are obtained.
