    Abstract: Three improved Grignard processes are used for preparing phenyl-containing chlorosilane products wherein the yield of diphenylchlorosilanes as a product is maximized, while the yield of phenylchlorosilanes as a product is minimized. In one embodiment, the process involves contacting a phenyl Grignard reagent, an ether solvent, an aromatic halogenated coupling solvent and a trichlorosilane. In another embodiment, the process involves contacting a phenyl Grignard reagent, an ether solvent, an aromatic halogenated coupling solvent, a trichlorosilane, and a phenylchlorosilane. In yet another embodiment, the process involves contacting a phenyl Grignard reagent, an ether solvent, an aromatic halogenated coupling solvent, and a phenylchlorosilane. In each embodiment, the reactants are present in particular mole ratios of the components.

    Abstract: A method in which radical polymerization of a vinyl monomer is initiated by an ozonide group attached to a silane or a siloxane polymer. The method is particularly useful for preparing organic polymers having a silicone chain end, or for preparing wide ranges of silicone/organic polymers and copolymers with varied architecture, i.e., ABA block copolymers, comb polymers, star polymers, and hyper-branched polymers. In one embodiment, the method is carried out by simply heating a vinyl monomer in the presence of a silane containing ozonide functionality. The ozonide silane is obtained by exposing silanes or siloxanes having an alkyl group containing a double bond to ozone. Surprisingly, an ozonide attached to an organosilicon compound was found to be stable, and capable of initiating vinyl polymerization upon heating to moderate temperatures, i.e., about 70.degree. C.

    Abstract: Polysiloxanes having pendant and/or telechelic carbonyl functionality, i.e., aldehyde functionality .tbd.Si--R--CH.dbd.O or ketone functionality .tbd.Si--R--CR.dbd.O, are manufactured in high yield by ozonolysis of polydiorganosiloxanes containing alkenyl groups, followed by treatment with a reducing agent such as zinc and acetic acid. The process is relatively fast and economical using readily available starting materials such as hexenyl-functional polymers. In particular, aldehyde functionality on the polymer can be used as a polymeric crosslinking agent.
