(57) [Abstract] [Purpose] To provide a crystalline synthetic resin composition having greatly improved transparency and improved physical properties such as mechanical strength. The crystalline synthetic resin composition of the present invention comprises (a) an alkali metal carboxylate, an alkali metal β-diketonate and an alkali metal β in 100 parts by weight of the crystalline synthetic resin. 0.01 to 5 parts by weight of at least one selected from the group consisting of ketoacetic acid ester salts and (b) at least one of cyclic organophosphoric acid ester metal salts represented by the general formula (I) of the following chemical formula 1 0 0.01 to 5 parts by weight is compounded. [Chemical 1] (In the formula, R 1 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, R 2 and R 3 each represent a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, and M represents a periodic table element. Represents a group II or group III metal atom, and a represents the valence of the metal represented by M.) |
