FIELD: chemistry of polymers. SUBSTANCE: present invention describes solid catalyst components for polymerization of olefins obtained by prepolymerization of at least two types of alpha-olefins on olefin polymerization catalyst comprising solid catalyst titanium component, catalyst organometal components and optionally electron donor to olefin polymerization catalyst comprising said solid catalyst component for polymerization of olefins, catalyst organometal component and optionally electron donor. The present invention also describes methods of polymerization of olefins using said olefin polymerization catalyst. Polyolefin particles having low adhesion to each other and also homogeneous particle distribution even when these particles contain large amount of amorphous polyolefin fraction. EFFECT: more efficient preparation method. 11 cl, 5 tbl
