mpound) and BMC (Bulk molding compound), the purpose of using these thermoplastic polymers is to reduce the shrinkage of molded products, that is, to improve the dimensional accuracy, and it is necessary to disperse them uniformly in the molding material. There is. Therefore, as the thermoplastic polymer, one having a melting point of less than 170 ° C., one having a very fine powder, or one easily dissolved in a crosslinking agent monomer such as styrene is used, and therefore a molding material is used. It was in the form of coarse particles and was not dispersed therein. Therefore, a molded product obtained by molding the molding material also became opaque and had no decorative value as the object of the present invention.

である。On the other hand, the thermoplastic polymer particles, which are an essential component of the present invention, need to have a melting point of 170 ° C. or higher and be transparent. The reason is that unsaturated polyester resin molding materials are pressure-molded at a mold temperature of 140 to 170 ℃,
If the melting point of the transparent thermoplastic polymer is lower than 170 ° C,
During molding, the transparent thermoplastic polymer melts and the shape of the particles collapses, and in the kneading step during the production of the molding material, the other components are uniformly mixed and lose transparency, resulting in a molded article that is preferable in appearance. This is because the disadvantage that it cannot be obtained occurs.
