摘要： 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

摘要： Thermosetting (meth)acrylate molding liquid resin consisting of a specified type of unsaturated oligourethane and alkyl (meth)acrylate within a specified range of ratio. Such a specified type of unsaturated oligourethane may be obtained by reaction between 2-isocyanatoalkyl (meth)acrylate and polyhydric alcohol or by reacting 2-isocyanatoalkyl (meth)acrylate with polyhydric alcohol at molar ratio of functional groups NCO/OH between 1.1 and 1.6 to form a urethane compound and reacting hydroxyalkyl (meth)acrylate with a residual portion of 2-isocyanatoalkyl (meth)acrylate at molar ratio of functional groups OH/NCO between 1.0 and 1.5. This invention also includes molding compositions containing such liquid resin and a specified type of inorganic filler and/or a certain type of thermoplastic high molecular compound as well as molded objects obtained by curing such compositions in a mold.
