PROBLEM TO BE SOLVED: To provide a polymer composition having excellent mechanical strength by comprising a crystallization agent that provides sufficient effect in a small addition amount. SOLUTION: This crystalline polymer composition comprises a crystalline polymer, a compound represented by general formula (I) (wherein R<11> , R<12> , R<21> and R<22> are each a 1-4C alkyl group; M<1> is an alkaline metal atom; and n is 1 or 2), and a metal salt component of a phosphoric acid ester (A) represented by general formula (II). It is preferable that the composition further comprises a metal salt component of an aliphatic organic acid (B).
