SILICON-CONTAINING PREPOLYMER CAPABLE OF PROVIDING SILICON-HYDROGEL WITH HIGH OXYGEN PERMEABILITY, HIGH TRANSMITTANCE, HIGH ELASTICITY, AND HIGH MOISTURIZATION

摘要

PURPOSE: A silicon-containing prepolymer is provided to be used as a reactant of a silicon-hydrogel, and to able to provide a silicon-hydrogel with high oxygen permeability, high transmittance, high elasticity, and high moisturization.;CONSTITUTION: A silicon-containing prepolymer is represented by chemical formula 1. In chemical formula 1, n is an integer from 1-20, A is a divalent aliphatic group or aromatic group, Y is H or -C(O)NH-Ry, Ry is a fluorine-containing aromatic group, fluorine-containing ether group, ether group or an amino group-containing group, X is O or-NRx-. Rx is H or a C1-5 monovalent alkyl group or -C(O)NH-Ry, Z is a group comprising an alkenyl group, and E is a divalent siloxane group.;COPYRIGHT KIPO 2013
