Abstract
The present invention is directed to a method for producing a semi-IPN composite, including: mixing a polyurethane (A) and a polymerization product (B) of a hydrophilic acrylic monomer (b1) and an acrylic monomer (b2) having a hydrolyzable silyl group; and causing the polymerization product (B) to undergo crosslinking. The hydrophilic acrylic monomer (b1) preferably includes an acrylic monomer (b1-1) having an amide group and an acrylic monomer (b1-2) having an oxyethylene group. Further, the polymerization ratio (molar ratio) 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 {(b1-1)/(b1-2)/(b2)} is preferably in the range of 50/49.5/0.5 to 89/1/10.
