Zusammenfassung:	PROBLEM TO BE SOLVED: To provide olefin based polymer particles with high stereoregularity, high melting point, high molecular weight and reduced ash content, and to provide a method for producing the same. SOLUTION: The olefin based polymer particles satisfy following requirements at the same time. (1) The polymer has less than 4.0 of molecular weight distribution (Mw/Mn) measured by GPC, (2) The polymer particles have minimum particle diameter of ≥3 μm and average particle diameter of ≥20 μm, (3) The polymer particles have ash contents of ≤2000 wt.ppm, (4) The polymer particles have ≤10 wt.ppm, of Si content and (5) The polymer particles contain a contact product of an aluminoxane and a diol compound.
