CATALYST COMPONENTS FOR POLYMERISATION OF OLEFINS Russian patent published in 2018 - IPC C08F4/651 C08F110/06 C08F4/654 

FIELD: CHEMISTRY.

SUBSTANCE: INVENTION RELATES TO CATALYST COMPONENTS FOR THE POLYMERIZATION OF OLEFINS. SOLID CATALYST COMPONENT FOR THE POLYMERIZATION OF OLEFINS CONTAINS MG, TI, CL AND, AT LEAST AN ELECTRON-DONOR COMPOUND OF FORMULA (I), WHERE Z IS C, WHERE THE GROUPS R², THE SAME OR DIFFERENT FROM EACH OTHER, ARE HYDROGEN OR C₁-C₂₀ HYDROCARBON RADICALS, THAT CAN BE COMBINED TOGETHER TO FORM ONE CYCLE, M IS A NUMBER EQUAL TO THE VALENCE OF Z, AND N IS AN INTEGER FROM 1 TO 10, X REPRESENTS O OR S, Y IS A GROUP -or³, -nr⁴r⁵ OR r⁶, IN WHICH r¹ AND r³ REPRESENT C₁-C₅ LINEAR ALKYL GROUP, r⁴-r⁵ GROUPS ARE INDEPENDENTLY HYDROGEN OR GROUPS r¹, AND GROUP r⁶ HAS THE SAME MEANING AS THE GROUP r¹, OR REPRESENTS A PHENYL RING, OR A PHENYL RING MONOSUBSTITUTED BY A SUBSTITUENT BELONGING TO c₁-C₁₀ ALKYL GROUP OR HALOGEN. CATALYST FOR THE POLYMERIZATION OF OLEFINS CONTAINS THE REACTION PRODUCT BETWEEN THE SOLID CATALYST COMPONENT AND THE ALKYL ALUMINUM COMPOUND. METHOD OF (CO) POLYMERIZATION OF OLEFINS CH₂=CHr' IN THE PRESENCE OF A CATALYTIC SYSTEM IS ALSO PROPOSED, WHERE r' IS HYDROGEN OR A HYDROCARBON RADICAL HAVING FROM 1 TO 12 CARBON ATOMS.

.

EFFECT: GOOD BALANCE OF CHEMICAL ACTIVITY AND STEREOSPECIFICITY.
