METHOD FOR PREPARING BIOCOMPATIBLE POLYMER, BIOCOMPATIBLE POLYMER AND USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method for preparing a biocompatible polymer comprising epsilon-linked L-lysine having free alpha-amino and carboxy functions, and to provide a contact lens and intraocular lens made from the polymer.SOLUTION: A method includes: preparing a monomer, which has 2-methylated, 2,3-dimethylated or unmethylated maleic acid anhydride, or substituted or unsubstituted vinylic or acrylic phthalic acid anhydride, and ethylenically unsaturated group; polymerizing the monomer to obtain a lens; and exposing the lens to L-lysine to amidate succinylic anhydride groups present in the lens.
