CATALYTIC SYSTEM ON THE BASE OF METALLOCENE FOR POLYMERIZATION OF ALKENES HAVING 2-10 CARBON ATOMS AND METHOD FOR PRODUCTION OF POLYMERS OF ALKENE HAVING 2-10 CARBON ATOMS

摘要

FIELD: catalytic chemistry. SUBSTANCE: proposed catalytic system comprises as active component at least one complex of metals from IV and V side groups of Periodic Table and at least one oligomer alumoxane compound. Said catalytic system additionally contains at least one cyclic compound of boron with formula (I) . In mentioned above formula R-R² represent alkyl groups with 1-10 carbon atoms which may be 1-3-fold substituted by atoms of halogen, by aryl groups having 6-15 carbon atoms or by alkoxyl groups having 1-10 carbon atoms, cycloalkyl groups with 4-7 carbon atoms which may be 1-3-fold substituted by atoms of halogen, by alkyl groups with 1-10 carbon atoms or by alkoxyl groups with 1-10 carbon atoms, alkoxyl groups with 1-10 carbon atoms which may be 1-3-fold substituted by atoms of halogen, by alkoxyl groups with 1-10 carbon atoms or by aryl groups with 6-15 carbon atoms, aryl groups with 6-15 carbon atoms which may be 1-5-fold substituted by atoms of halogen, by alkyl groups with 1-10 carbon atoms or by alkoxyl groups with 1-10 carbon atoms. Proposed method for production of alkenes having 2-10 carbon atoms is carried out by polymerization of suitable alkene in the presence of mentioned above catalytic system. EFFECT: improves quality of desired product, improves efficiency of the method.
