Title:
ANTIMICROBIAL POLYMER, CONTACT LENS, AND CONTACT LENS CARE PRODUCTS
Document Type and Number:
WIPO Patent Application WO/1995/002617
Kind Code:
A1
Abstract:
An antimicrobial polymer prepared by homo- or copolymerizing a vinylphosphonium salt monomer such as 2-methacryloxyethyltri-n-octylphosphonium chloride. A contact lens and contact lens care products both based on an antimicrobial resin comprising a copolymer of a polymerizable monomer with a vinylphosphonium salt monomer. The antimicrobial polymer has a wide antimicrobial spectrum and a sufficient antimicrobial effect even with a short contact time. The lens and lens care products scarcely suffer from microbial contamination and are excellent in optical performance and processability.
