Abstract
Quickly curable unsaturated polyester composition with improved surface characteristics and stability in storage contains 20-40 weight parts of unsaturated polyester, 20-60 weight parts of vinyl monomer, 0.01-1.0 weight parts of BHT (ditertiary butyl hydroxy toluene), and 10-40 weight parts of thermoplastic resin such that the total is 100 weight parts. In addition, 0.001-0.1 weight parts of compound with effect of inhibiting polymerization at temperatures over 100.degree. C. are contained against the total of 100 weight parts. Molding materials are obtained by impregnating glass fibers with such compositions and products are obtained by curing such molding materials.
