アリン酸マグネシウム)である場合に比して、格段に各
強度物性が大ぎい。As shown in the examples below, a molded article molded using a FRPP resin composition that meets the requirements of the present invention, that is, the dispersant is PE wax, has a dispersant that is a fatty acid metal salt (magnesium stearate). Compared to other cases, each strength and physical property is significantly greater.

It is now possible to provide molded products with impact resistance and gray color specifications.
成形品に充分な強度物性が得られる理由は、断定できな

なり、大きな強度物性が得られる。When a fatty acid metal salt is used as a dispersant for a coloring component, the fatty acid metal salt crushes the carboxyl groups in the modified PP, reducing the effect of blending the modified PP (improving adhesion with reinforcing fibers), and causing the polymer and reinforcing In contrast, in the case of the present invention, since PE wax is used as a dispersant, such a phenomenon does not occur. Adhesive properties are improved, and greater strength and physical properties can be obtained.
