Title: METHOD FOR PRODUCING SEMI-IPN COMPOSITE
Abstract:
The present invention pertains to a method for producing a semi-IPN composite, the method being characterized by mixing a polyurethane (A) with a polymer (B) of hydrophilic acrylic monomers (b1) and acrylic monomers (b2) having a hydrolyzable silyl group, to cross-link the polymer (B). The hydrophilic acrylic monomers (b1) preferably include an acrylic monomer (b1-1) having an amide group and an acrylic monomer (b1-2) having an oxyethylene group. In addition, the polymerization ratio (molar ratio) (b1-1)/(b1-2)/(b2) of the acrylic monomer (b1-1) having an amide group, the acrylic monomer (b1-2) having an oxyethylene group, and the acrylic monomer (b2) having a hydrolyzable silyl group is preferably within the range of 50/49.5/0.5 to 89/1/10.
