Abstract
An organopolysiloxane having at least one group of the formula <FORM:1015402/C3/1> wherein R1 is an alkylene radical of up to 12 C atoms, R11 is an alkylene radical of 2 to 4 C atoms and the group (OR11)n is such that the overall ratio of C/O is from 2:1 to 3:1, R111 is R, OR, OOCR or OOCH, X is OR, OOCR or OCOOR, where R is a monovalent organic radical free of olefinic unsaturation, n is an integer from 5 to 90 and m is 1,2 or 3, may be made by reacting a polyalkyleneoxysilane containing an ethylenically unsaturated linkage with a polysiloxane containing at least one H atom bonded to Si, preferably at 80 DEG to 100 DEG C., and, if desired, in the presence of a catalyst, e.g. a complex of an olefin with a platinous halide, platinized charcoal, iridium chloride, ruthenium chloride and chloroplatinic acid. In another method a silane, e.g. (b -organopolysiloxanylethyl)-methyldichlorosilane, is reacted with a polyalkylene oxide. The siloxanes may be linear, branched chain or cyclic, and preferably contain from 10 to 20 of the above groups per 100 Si atoms. In a typical example (1) a benzene solution of a cyclohexene/platinous chloride complex was added to a mixture of a linear dimethylpolysiloxane containing 20 Si atoms and 3 Si-H groups and the resulting mixture was heated at 90 DEG C. to yield a product which was then reacted with a polyalkyleneoxide, containing equal numbers of ethyleneoxy and propyleneoxy units, to yield the desired product. Uses: as surfactant in the preparation of polymethane foams.
