고함수율 중합체의 제조방법Process for producing high water content polymer

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

Claims (3)

N-비닐락탐에 소량의 가교제와 개시제를 함께 첨가하여 그 분자량이 10내지 10.000에 다다를 때까지 중합을 시킨 다음, 거기에다 소량의 개시제가 함유되어 있는 메타크릴산 에스테르를 서서히 첨가시키면서 혼합하여 공중합 시키므로써 소프트 콘택트 렌즈용 중합체를 제조하는 방법.A small amount of crosslinking agent and initiator are added to N-vinyllactam and polymerized until its molecular weight reaches 10 to 10.000, and then mixed and copolymerized with a small amount of methacrylic acid ester containing a small amount of initiator. A method for preparing a polymer for a soft contact lens. 제1항에 있어서, N-비닐락탐은 N-비닐피롤리돈을 사용함을 특징으로 하는 방법.The method of claim 1, wherein the N-vinyllactam uses N-vinylpyrrolidone. 제1항에 있어서, 메타크릴산에스테르는 메틸메타크릴레이트를 사용함을 특징으로 하는 방법.The method according to claim 1, wherein the methacrylic acid ester is methyl methacrylate. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
