The present invention provides a curable resin composition comprising: a polymer (A) containing a polymerizable unsaturated bonding group; and a polymerizable unsaturated monomer (B). Polymerizable unsaturated monomer (B) comprises as an essential component an oligoalkyl(C.sub.2 -C.sub.4)ether(n=2-15)-monoalkoxy(C.sub.1 -C.sub.18)-(meth)acrylate. This curable resin composition according to the present invention displays superior adherence, air-drying, water resistance, and storage stability properties in addition to a reduced odor.

Curable resin composition and coating material composition

A fluoroolefin copolymer having an inherent viscosity of from 0.05 to 2.0 dl/g and composed of

Fluoroolefin copolymer, process for production thereof and composition

A process for producing an easily handleable sheet molding compound which comprises impregnating glass fibers with a resin composition comprising (A) an unsaturated polyester having a hydroxyl value of 20 to 55 and an acid value of 5 to 20 with a hydroxyl value/acid value ratio of from 1.7 to 10, (B) a polymerizable monomer and (C) a polyisocyanate compound having not more than 20 carbon atoms excepting the carbon atoms of the isocyanate groups and selected from the group consisting of diisocyanates and polymethylenepolyphenyl isocyanates, the proportions of the unsaturated polyester (A) and the polyisocyanate compound (C) being such that the mole ratio of the hydroxyl groups of the unsaturated polyester (A) to the isocyanate groups of the polyisocyanate compound (C) is from 0.7 to 1.3, and said composition being free from an oxide or hydroxide of magnesium or calcium, said impregnation being effected so that the glass fiber content becomes 40 to 75% by weight; and molding the resin-impregnated glass fibers into a sheet.
