FIELD: chemistry.
SUBSTANCE: invention relates to method of obtaining impact propylene copolymer with low content of volatile organic compounds, composition based on impact propylene copolymer and product based on it. Method includes contact of propylene with catalytic composition, including substituted 1,2-aromatic phenylene diether in polymerisation conditions in first polymerisation reactor. Propylene-based active polymer formed in first reactor contacts with at least one olefin in conditions of polymerisation in second reactor. Formed in second reactor impact propylene copolymer contains substituted 1,2-aromatic phenylene diether.
EFFECT: impact propylene copolymer obtained in accordance with invention possesses high rate of melt outflow and low content of volatile compounds.
