PURPOSE:To obtain the title composition decreased in local heat buildup in curing in molding and giving a molded item improved in surface properties and dimensional stability by forming a suspension composition containing a polymerizable molding composition and specified organic filler. CONSTITUTION:A polymerizable molding composition (A) which can form a resin without forming any volatile component when cured, for example, styrene, is mixed with a fine polymer obtained by precipitation from a solution containing a liquid polymerizable component constituting A or part of A and a polymer (B) which forms fine polymer, for example, an unsaturated polyester (the mixing ratio is generally such that 0.5-50 pts.wt. B is present per 100 pts.wt. A) to form a polymerizable molding composition comprising a matrix of A in which B is homogeneously dispersed. |
