Abstract
Radical polymerizable liquid resins contain unsaturated urethane of a specified structure and vinyl monomers at weight ratio of (unsaturated urethane)/(vinyl monomers)=10/90-90/10. The unsaturated urethane has (meth)acryloyl and higher aliphatic hydrocarbon groups in its molecule, and the vinyl monomers are copolymerizable with this unsaturated urethane. Radical polymerizable liquid resin compositions are obtained by adding inorganic powder filler to such radical polymerizable liquid resins In-mold cured products obtained from such radical polymerizable resins or radical polymerizable resin compositions have improved water resistance and other favorable properties
