<p><P>PROBLEM TO BE SOLVED: To provide a curing method of raising the curing rate of a molding material without using a transition metal salt of an organic acid, and providing a cured product having little residue of an unsaturated monomer. <P>SOLUTION: The curing method, in which a molding material containing a curing accelerator composition and an unsaturated polyester is heated and cured, uses the curing accelerator composition comprising only an organic peroxide composed of a peroxy monocarbonate or a peroxy ester (the blend amount is 0.1 to 10 pts.mass based on 100 pts.mass of the unsaturated polyester resin), andα-acetyl-γ-butyrolactone (the blend amount is 0.01 to 5 pts.mass based on 100 pts.mass of the unsaturated polyester resin), and is carried out at a heating-curing temperature of 100 to 180°C. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
