リエステル樹脂成形材料の流動性を改良し、更に。However, unsaturated polyester resin molding materials containing 8% or less of copolymerizable monomers with a flash point of 40°C or lower are extremely hard.
In addition to requiring high molding pressure when molding in a mold, the fluidity of the unsaturated polyester resin molding material is poor, making it impossible to mold a defect-free molded product. By using a copolymerizable monomer with an unsaturated polyester at a temperature of 40°C or higher, the fluidity of the unsaturated polyester resin molding material is improved.
