Abstract: A novel synthetic route to new classes of polymeric coupling agents using substituted epoxy monomers is reported. In the presence of an initiating agent and tris(pentafluorophenyl)borane catalyst, substituted epoxy monomers bearing polyalkylene oxide and trialkoxysilane moieties undergo a ring-opening polymerization. The polymerization is highly versatile and allows for the fine-tuning of functional, structural, and architectural features of the resulting polymeric coupling agents. These new polyalkylene oxides substituted with organosilyl groups are capable of bonding to and modifying inorganic surfaces. The products of this invention form thin hydrophilic films.

Abstract: Compositions which undergo cure by irradiation with UV, visible light or electron beam only after activation by hydroxylated surfaces or exposure to moisture are based on mixtures of cyclic thiasilanes and unsaturated silanes, siloxanes or hydrocarbons.

Abstract: A stabilized mixture containing an alkyltrialkoxysilane hydrolysate solution and an amine functional silicone emulsion is provided. The stabilized mixture may be utilized in a masonry treatment product or a cellulosic or wood treatment product, such as to provide waterproofing properties, or in a hair care treatment product for improving hair combability. A method of preparing the mixture involves hydrolyzing an alkoxysilane to form an aqueous solution containing alkylsilanetriols and/or oligomeric alkylsilanetriol condensates; and stabilizing the solution by adding an amine functional silicone.

Reaction products, derivatives, and methods of making these materials are also described.

Abstract: Nanocomposites exhibiting elongation exceeding about 2000%, elastic recovery, and tensile strength exceeding 2.5 MPa are described. A method these elastomers involves performing a catalyzed step growth polymerization of a heterobifunctional siloxane macromonomer compounded with at least about 15 wt % surface passivated silica nanoparticles. The macromonomer has a degree of polymerization of at least about 40 and the silica nanoparticles have nominal diameters of less than about 50 nm.

Abstract: A convenient, practical method for forming elastomers from dual functional siloxanes that cure by a step-growth mechanism is provided. The method involves preparing a first mixture containing a first telechelic siloxane and a hydrosilylation catalyst; preparing a second mixture containing a second telechelic siloxane and a dual functional siloxane having two different polymer termini; and reacting the first mixture with the second mixture to produce the siloxane elastomer. The first and second mixtures may be stored separately until time of use.

Abstract: Linear siloxane polymers having low viscosities, precise molecular weights and two distinct polymer termini are provided. Preferred viscosities are greater than 5 cSt and less than 20,000 cSt, and the preferred functionalities at the polymer termini are one hydrogen and one vinyl group, each attached to a silicon atom. Methods for producing such siloxane polymers are also described In the presence of catalysts, such as Pt0 complexes, these siloxanes undergo step-growth polymerization to form elastomers at temperatures below 150° C.
