摘要:
The present invention relates to fiber treatment compositions comprising an unsaturated acetate, an organohydrogensiloxane, a metal catalyst, an organosilicon compound, and optionally a dispersant. The compositions of the present invention impart beneficial characteristics such as slickness, softness, compression resistance and water repellency to substrates such as fibers and fabrics.
摘要:
Novel silicone acrylate polymers and a method for their preparation is disclosed. These polymers are formed from silicone acrylates, silicone diacrylates, or mixtures with organic acrylates. The copolymer formed from the reaction mixture of silicone acrylates and organic acrylates is useful in enhancing glass reinforced polyesters.
摘要:
A process of curing and cross-linking methylhydrosiloxanes by contacting and forming a mixture of an allyl amide with at least one methylhydrosiloxane in the presence of a Group VIII metal catalyst, and heating the mixture of the allyl amide, the methylhydrosiloxane, and the Group VIII metal catalyst, in the presence of ambient moisture until the methylhydrosiloxane becomes cured and cross-linked.
摘要:
The present invention provides a method for preventing or reducing haze development in a beverage. Silane-treated silica filter media are synthesized. By contacting the beverage with the silane-treated silica filter, one or more haze-forming components bind to the silane-treated silica filter media and are removed by filtration. In addition, particulates in the beverage are removed by filtration. Beverages that tend to develop haze on standing and/or chilling such as alcoholic, fruit, and vegetable beverages, are suitable for the present invention. This haze in a beverage is mainly caused by polyphenols and proteins. The present invention provides a method that can reduce the levels of both polyphenols and proteins. The silica filter media useful for the present method include rice hull ash, oat hull ash, or diatomaceous earth.
摘要:
A bonded phase material useful with a chromatographic separation process. The bonded phase material includes a hydroxyl bearing porous material, a first controlled stoichiometric amount of a first interactive silane covalently bonded to the surface of the hydroxyl bearing porous material and at least one additional interactive silane covalently bonded to the surface of the hydroxyl bearing porous material to provide the porous material with a gradient of functionality of varied polarity creates a unique overall polarity which is not obtainable by the separate interactive silanes themselves. The method of silating the porous material includes sequential application of controlled stoichiometric amounts of the interactive silanes.
摘要:
An emulsion is made by dispersing a siloxane in water by forming a mixture of water, a cyclic siloxane, and an ethoxylated alcohol nonionic surfactant. An organosilanolate initiator is used, and the mixture is free of other surfactants which bear a charge. The cyclic siloxane is polymerized until an emulsion is formed, and the emulsion is free of electrical charge. The emulsion is more compatible in the personal care arena.
摘要:
The polymer latices of this invention are compositions formed by adding an unsaturated alkoxy silane and an initiator to a preformed emulsion polymer. The polymer latices have utility as protective surface coatings, adhesives, sealants and as vehicles for paint formulations.
摘要:
The present invention relates to catalyst compositions and methods for the preparation thereof. More particularly, the present invention relates to novel rhodium catalyst complexes compositions useful the crosslinking of compositions containing methylhydrogensiloxanes. The present invention further relates to a method for the preparation of these novel catalyst complexes and to their use in emulsions of methylhydrogensiloxanes which are used to treat fibers or fabrics.

摘要:
The present invention relates to coating compositions containing multifunctional acrylate monomers, acrylic monomers and colloidal silica. Silanes are absent from these coating compositions. Transparent, abrasion resistant coatings result from the cure, either by ultraviolet light or electron beam radiation, of these compositions.
