Abstract: The invention relates to a process for the manufacture of organomonosilanes bearing both hydrogen and chlorine substituents at the silicon atom by subjecting a silane substrate comprising one or more silanes selected from organomonosilanes, organodisilanes and organocarbodisilanes, with the proviso that at least one of these silanes has at least one chlorine substituent at the silicon atom, to a redistribution reaction in the presence of a phosphane or amine acting as a redistribution catalyst.

Abstract: A coating composition is shown and described herein. The coating composition comprises: the (meth)acrylic polymer containing at least one active hydrogen (a), the epoxy silane oligomer composition (b), emulsifier (c), titanium oxide particles (d), a siliceous particulate filler (e) and water (f) optionally one or more additives, where the epoxy silane oligomer composition comprises 5 to 15 weight percent monomer, 5 to 20 weight percent dimer, 5 to 20 weight percent trimer and 45-85 weight percent poly-oligomers components. The coating composition can provide a water-based coating composition exhibiting early water resistance such that defects in the coating are minimized if exposed to water prior to the coating being fully cured.

Abstract: Reactive poly(fluoroalkyl-functional siloxane) oligomers, method of making the same, and compositions comprising the same are shown and described herein. The reactive poly(fluoroalkyl-functional siloxane) oligomers are is derived from a hydrolysable fluoroalkyl-functional silanes. Coating compositions comprising reactive poly(fluoroalkyl-functional siloxane) oligomer(s) may be used to form a coating or a film on a substrate and impart hydrophobic and/or oleophobic properties. The reactive poly(fluoroalkyl-functional siloxane) oligomer are more hydrophobic and oleophobic and show better chemical resistance than the hydrolysable fluoroalkyl-functional silane.

Abstract: A hydrophilic siloxane copolymer of siloxane and hydrophilic organic monomer/s The copolymers can be functionalized to make them capable of undergoing further polymerization by thermal or actinic radiations. The hydrophilicity of these polymers can be varied by varying the siloxane versus organic monomer ratio thereby going from water dispersible to soluble states. The siloxane content can be tuned accordingly in order to provide moderate to high oxygen permeability. These copolymers can be used as a single component curable composition which results in hydrogels to minimize the presence of leachable components thus by reducing the processing cost. The polymers may also find applications in personal care formulations as copolymers, film-formers, hydrogels, coating, emulsions/latex etc.
