摘要：
THERE IS DISCLOSED A PROCESS FOR HOMOPOLYMERIZING AT LEAST ONE DIOLEFIN OF THE GENERAL FORMULA:
H2C=C(-Y1)-C(-Y2)=CH-R
WHEREIN Y1 AND Y2 ARE SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND ALKYL RADICALS HAVING FROM 1 TO 4 CARBON ATOMS AND R IS SELECTED FROM ALKYL (INCLUDING CYCOALKYL), ALKARYL, ARYLALKYL AND ARYL GROUPS, CONTAINING FROM 1 TO 8 CARBON ATOMS, OR COPOLYMERIZING WITH AT LEAST ONE DIOLEFIN OF THE GENERAL FORMULA
H2C=C(-Y1)-C(-Y2)=CH2
WHEREIN Y1 AND Y2 ARE SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND ALKYL RADICALS HAVING FROM 1 TO 4 CARBON ATOMS, BY CONTACT, UNDER SOLUTION POLYMERIZATION CONDITIONS WITH A CATALYST COMPRISING (1) AN ORGANOALUMINUM COMPOUND FROM THE CLASS CONSISTING OF TRIORGANOALUMINUM AND DIOGRANOALUMINUM HYDRIDE COMPOUNDS, (2) AN ORGANOMETALLIC COMPOUND, THE METAL ION OF WHICH IS SELECTED FROM THE CLASS CONSISTING OF METALS OF GROUP III-B OF THE PERIODIC SYSTEM.
H2C=C(-Y1)-C(-Y2)=CH-R
