FLUORINE AND/OR SILICONE CONTAINING POLY(ALKYLENE-OXIDE)-BLOCK COPOLYMERS AND CONTACT LENSES THEREOF

摘要

6V-17628/1+2/+/CGC 1433 Fluorine and/or Silicone Containing Poly(alkylene-oxide)-block Copolymers and Contact Lenses Thereof Fluorine and/or silicone containing block copolymers are described which are thecopolymerization product of mono; di- or trivinyl substituted poly(alkylene oxide) prepolymers (A) and fluoroalkyl-alkylene acrylates or methacrylates (B1), oligosiloxy-silyl alkyl-acrylates or methacrylates (B2), and optionally other copolymerizable comonomers (C). The novel block copolymers are prepared in solution or bulk and are characterized by high oxygen permeability, flexibility and wettability and are therefore well suited as biocompatible polymers, especially as contact lenses.
