Abstract:
Organosilicon compounds are prepared by the addition reaction of a gaseous unsaturated hydrocarbon with a silane or siloxane containing at least one silicon-bonded hydrogen atom in the presence of a hydrosilylation catalyst in a liquid reaction medium. In this process the unsaturated hydrocarbon and optionally the silane or siloxane is dispersed into the liquid reaction medium by a jet eductor (also known as a venturi pump) device and the resultant gas-in-liquid dispersion is introduced into a bubble reactor.

Abstract:
The present invention describes novel non-hydrolyzable, linear, random block copolymers comprising units of polysiloxanes and polyalkyleneoxides linked by bis-aminofunctional groups. These copolymers have been successfully applied as textile enhancers as well as conditioning agents for hair and skin care products.
Abstract:
A method for providing a flexible hardcoat on a substrate includes the use of a dual cure silane possessing a UV curable group and a thermally curable silane group. The dual cure silane hydrolyzed and a portion of the silanol groups are condensed with silica to provide a fluid coating composition which is then applied to a substrate. A first cure with UV radiation causes the coating to harden into a flexible hardcoat which permits the substrate to be thermoformed or embossed without damage to the coating. The substrate is then heated to thermally cure the hardcoat to provide a fully cured hard and abrasion resistant hardcoat.
Abstract:
The present invention relates to polyurethane foam prepared from a polyurethane foam-forming reaction mixture possessing a silicone copolymer surfactant, methods for making the surfactant, and a process for preparing low density polyurethane foams.
