Abstract:
A moisture-curable composition is shown and described herein. The moisture-curable composition comprises a moisture-curable resin and a moisture scavenger selected from a cyanoalkylalkoxysilane. The inclusion of the cyanoalkylalkoxysilane in the moisture-curable composition has been found to effectively scavenge moisture and control the rate of curing and viscosity increase in the composition.
Abstract:
A linear silicone polymer suitable for use in producing homopolymers, copolymers, polymerized emulsions, latex compositions, and hydrogel polymer films. In one aspect, a hydrophilic silicone monomer is of the Formula 1: WAmBnW (1) Where, A is a divalent block comprising a silicone-containing pendant group. In one embodiment, the silicone-containing pendant group comprises polyalkylene oxide groups. The structure of the polymer can be controlled and tuned to provide a material with excellent wettability and oxygen permeability. The polymers are suitable for use in a variety of applications including in providing a film for forming contact lenses.
