    摘要： The present invention relates to an organosiloxane compound suitable for the modification of silicone rubbers and synthetic resins, an organosiloxane compound useful as its intermediate, and a process for preparing them. The organosiloxane compound of the present invention can be represented by the general formula (IV) ##STR1## wherein j is an integer of 1 to 2000, R is an alkyl group having 1 to 4 carbon atoms, and R.sup.1 is a pentafluorophenyl group or a straight-chain or a branched fluoroalkyl group represented by the formula (III)C.sub.1 H.sub.b F.sub.2a-b+1 (II)wherein a is an integer of 3 to 18, and b is an integer of 0 to 2a.The siloxane compound of the present invention has a siloxane chain each having a substituent with a fluorine atom containing group at the terminal thereof. Each of molecules constituting the polysiloxane compound of the present invention has a terminal hydrosilyl group portion and a fluorine atom-containing terminal substituent portion therein. Since the reactive group of the hydrosilyl group is chemically bonded to the synthetic resins, the deterioration in characteristics with time can be hindered. The synthetic resins can be provided with the specific function of the fluoroalkyl group without impairing characteristics which the polysiloxane has.

    摘要： A polyorganosiloxane compound contains a fluorine-containing substituent at least at its .alpha.-, .alpha.'- or .alpha."-position and a substituent having an epoxy linkage at its .omega.-position. The polyorganosiloxane compound can provide a synthetic resin with properties which cannot be provided by conventional polysiloxane compound by incorporating the polyorganosiloxane compound into the synthetic resin through a chemical linkage via the epoxy linkage thereof and a group reactive with the epoxy linkage thereof.
