摘要： Aesthetically attractive, free standing dispensers for the controlled release of volatile liquid materials such as perfumes and fragrances into the atmosphere consist essentially of composite hydrogels comprising a continuous phase of a solubilized polyvinyl alcohol, a dispersed phase comprising a polyelectrolyte and an aqueous solution of the volatile liquid that is distributed between said continuous and dispersed phases. The exterior surfaces of the dispenser remain dry to the touch throughout its useful life.

摘要： What is disclosed herein are new and novel hydrogel soaps and a process for obtaining them which comprises providing surface active agents in a pre-hydrogel mixture, and then forming the hydrogel. The process affords solid soaps which do not change significantly in size during use, have wide varying mechanical properties including high strengths in spite of the very high water content of the soaps, and moreover, unexpectedly provide uniform release of the surfactants and/or detergents slowly over a long period of time.

摘要： Organosilicon aldehydes and ketones are prepared by a method in which an organosilicon compound containing ozonide functionality is first formed by exposing an organosilicon compound containing unsaturation to ozone. The organosilicon compound containing ozonide functionality is then reduced to the corresponding organosilicon aldehyde or ketone with a reducing agent. One preferred reducing agent is a combination of zinc and acetic acid. Complete conversion of the ozonide to the carbonyl (.dbd.C.dbd.O) compound is obtained when the ozonide containing the reducing agent is heated briefly to about 30.degree. C.

摘要： A method for neutralizing a polyorganosiloxane mixture. The method comprises (A) contacting a mixture comprising a polyorganosiloxane and an acid with a neutralizing amount of a solid organic base at a mixture temperature above the melting temperature of the solid organic base forming a molten organic base and forming an insoluble adduct of the acid with the molten organic base, (B) lowering the mixture temperature to effect solidification of residual molten organic base to residual solid organic base, and (C) effecting separation of the insoluble adduct and the residual solid organic base from the polyorganosiloxane mixture. The present invention is especially useful for neutralizing mixtures comprising polyorganosiloxane mixtures where the polyorganosiloxane comprises hydrogen atoms bonded to silicon.

摘要： A process for manufacturing high molecular weight polysiloxane copolymers by interfacial polymerization. The polysiloxanes may contain phenylmethyl siloxane blocks and dimethyl siloxane blocks, alternately polymerized together to form an (A.sub.m B.sub.n).sub.x type copolymer. The interfacial polymerization process is fast, proceeds smoothly at room temperature, and is not reversible, i.e., no cyclic siloxane species are generated. The polysiloxanes can be formed as thermoplastic elastomers suitable for use as sealants, fillers, and films.

摘要： An interfacial polymerization process wherein organosilicon reactants are dissolved in mutually immiscible, nonaqueous solvents, and a condensation product is formed at the interface. This technique has many of the advantages of analogous organic interfacial polymerization, and may be used, for example, to prepare crosslinked films, fibers, particles, or encapsulants. Structures which cannot be prepared by other routes can be made. In particular, a well-defined alternating dimethyl/diphenyl siloxane block copolymer can be prepared by condensing a dihalo organosilicon compound such as diphenyldichlorosilane (C.sub.6 H.sub.5).sub.2 SiCl.sub.2 in diphenyl ether with a dimethyl silanolate in cyclohexane. The advantages are ability to control polymer structure, and there is no rearrangement during polymerization.
