ABSTRACT:
The present invention relates to novel cyclic or linear allylpolysiloxane type silicone fluids having allylalkylsiloxy and diorganosiloxy groups as represented by the formula I and their preparation methods by hydrolyzing mixtures of allyldichlorosilane and diorganodichlorosilane as represented by the formula II and formula III respectively. ##STR1## wherein R is selected from the group consisting of hydrogen alkyl(C.sub.3 -C.sub.20), chloroalkyl, cyanoalkyl, fluoroalkyl, and phenylalkyl group; R.sup.x and R.sup.2 represent independentlhydrogen, methyl or phenyl group; M represents H or SiMe.sub.3 group wherein Me is methyl group and when M is hydrogen, the silanol groups at the both ends of the molecule easily undergo dehydration and cyclize to form the cyclic silicone fluids as represented by the following formula I'; the mixing ratio (x/y) of the compounds as represented in formula I and formula HI respectively can be 1:0.01-1:100; CH.sub.2 CH.sub.2 R.sup.3 of formula II equals to R of formula I or I'. ##STR2##
