摘要

PPROBLEM TO BE SOLVED: To provide a nonhydrous soft eye lens material in which the stickiness of the stock itself is suppressed, and which has excellent flexibility, elasticity, oxygen permeability, transparency and shape recoverability suitable as those of an eye lens material, and is obtainable by a simple method, and to provide a nonhydrous soft eye lens using the same. PSOLUTION: The nonhydrous soft eye lens material is composed of a copolymer of both-terminal vinyl polydimethylsiloxane represented by general formula (1), vinyl carboxylate ester and triallylisocianurate. The nonhydrous soft eye lens is obtained by using the same. In the formula, n is the integer of 200 to 1,000. PCOPYRIGHT: (C)2006,JPO&NCIPI
