FIELD: polymerization processes.
SUBSTANCE: invention discloses olefin(s) polymerization process comprising following stages: (i) preparing composition including C5-C30-alkane diluent and at least one catalytic compound and composition including mineral oil or silicone oil, substrate, activator, and optionally catalytic compound including group 15 element and also group 3-14 transition metal; (ii) continuously combining the two compositions to obtain catalytic composition; (iii) introducing this catalytic composition, one or several olefins and, optionally, hydrogen into working polymerization reactor; and (iv) recovering polymer.
EFFECT: improved physical and chemical properties of polymers.
