3d network-structured silicon-containing prepolymer and method for fabricating the same

Abstract

A 3D network-structured silicon-containing preploymer and a method for fabricating the same are disclosed. The method of the present invention undertakes a hydrolytic condensation/polymerization reaction of penta(alkynol)alkoxy solixane, a reactive silicon-containing polymer and a reactive hydrophilic monomer to form a silicon-containing preploymer featuring a 3D network structure and having superior mechanical strength. The method further undertakes a copolymerization reaction of the silicon-containing preploymer, a hydrophilic monomer and a silicon-containing hydrophobic monomer to fabricate a silicone hydrogel-containing mixture having high oxygen permeability and high hydrophilicity. The silicone hydrogel-containing mixture can be used to fabricate contact lenses that the users wear comfortably.
