  • Publication number: 20110263780
    Abstract: The present invention pertains to a process for producing unmeltable polysilane-polycarbosilane copolymers which are soluble in inert solvents, comprising the steps providing the product of a disproportionation of a methylchlorodisilane or a mixture of several methylchlorodisilanes of the composition Si2MenCl6-n, wherein n=1-4, wherein the disproportionation was carried out with a Lewis base as a catalyst, wherein this product is a chlorine-containing, crude polysilane/oligosilane containing hydrocarbon groups, and thermally postcrosslinking the crude polysilane/oligosilane to a polysilane-polycarbosilane copolymer, characterized in that the chlorine content of the polysilane-polycarbosilane copolymer is lowered by reacting the crude polysilane/oligosilane with a substitution agent, by which chlorine bound therein is replaced with a chlorine-free substituent. Green fibers and low-oxygen/oxygen-free ceramic fibers with a very low chlorine content can be produced using this process.

    Abstract: Inorganic/organic hybrid polymers containing silsesquioxane cages are robust and exhibit desirable physical properties such as strength, hardness, and optical transparency at infrared and ultraviolet wavelengths. The polymers are prepared by polymerizing functionalized polyhedral silsesquioxane monomers such as polyhedral silsesquioxanes bearing two complementarily reactive functional groups bonded to cage silicon atoms by means of spacer moieties. The spacer moieties allow for steric mobility and more complete cure than polyhedral silsesquioxanes bearing reactive functional groups bound directly to cage silicon atoms.

    Abstract: Substantially or roughly spherical micellar structures useful in the formation of nanoporous materials by templating are disclosed. A roughly spherical micellar structure is formed by organization of one or more spatially unsymmetric organic amphiphilic molecules. Each of those molecules comprises a branched moiety and a second moiety. The branched moiety can form part of either the core or the surface of the spherical micellar structure, depending on the polarity of the environment. The roughly spherical micellar structures form in a thermosetting polymer matrix. They are employed in a templating process whereby the amphiphilic molecules are dispersed in the polymer matrix, the matrix is cured, and the porogens are then removed, leaving nanoscale pores.

    Abstract: An apparatus includes an electronic component mounted on a substrate and metal conductors electrically connecting the electronic component. A conformal coating overlies the metal conductors and comprises a polymer into which a phosphine compound is impregnated and/or covalently bonded. Accordingly, the conformal coating is able to protect the metal conductors from corrosion caused by sulfur components (e.g., elemental sulfur, hydrogen sulfide, and/or sulfur oxides) in the air. That is, the phosphine compound in the polymer reacts with any corrosion inducing sulfur component in the air and prevents the sulfur component from reacting with the underlying metal conductors. Preferably, the phosphine compound in the polymer does not react with other components in the air (e.g., carbon dioxide) which would otherwise deplete its availability for the target reaction. The phosphine compound may be rendered completely non-volatile by covalently bonding it directly into the polymer backbone.

  • Publication number: 20110185947
    Abstract: The invention relates to a method for production of polyhydroxyfunctional polysiloxanes with branched polyglycidol polyether groups, in which firstly at least one allylic or methallylic starting material is reacted with at least one glycidol, such that an allyl polyether or methallyl polyether is formed, and then the allyl polyether or methallyl polyether thus produced is added to a Si—H functional alkyl polysiloxane in the presence of an acid buffering agent. The invention further relates to polysiloxanes, which may be obtained by said method and the use of the polysiloxanes in coating agents, polymeric coating masses and thermoplastics.

  • Publication number: 20110152459
    Abstract: The present invention is a release liner including a film formed of a thermoplastic polymer and a non-migratory silicone additive. The additive is formed with a siloxane polymer that can be added directly to the thermoplastic polymer prior to compounding the thermoplastic polymer into an extrudable release liner film. The additive provides the desired release properties to the film, and due to bonds formed between the siloxane polymer and a binding component added to the siloxane polymer during formation of the additive, as well as the high molecular weight of the siloxane polymer, is non-migratory.

    Abstract: A poly(arylene ether)-polysiloxane multiblock copolymer is prepared by the reaction of a hydroxy-diterminated poly(arylene ether), a hydroxyaryl-diterminated polysiloxane, and an aromatic diacid chloride. This synthesis overcomes disadvantages of known syntheses of poly(arylene ether)-polysiloxane block copolymers. The poly(arylene ether)-polysiloxane multiblock copolymer is useful for improving the melt processibility of poly(arylene ether) compositions.
