A process which comprises polymerizing ethylene with an alpha-olefin, CH2═CHR, wherein R is a saturated aliphatic radical with 2 or more carbon atoms or a cycloaliphatic radical, in the presence of a catalyst obtained by reacting an aluminum alkyl compound with a catalytic titanium halide compound.
A process comprising polymerizing ethylene with an alpha olefin, CH2═CHR, wherein R is a saturated aliphatic radical with two or more carbon atoms or a cycloaliphatic radical, in the presence of a catalyst made from a reaction between (a) a chloride of titanium with (b) an aluminum alkyl compound.
A process for preparing a copolymer comprising copolymerizing monomeric olefin molecules comprising a monomeric vinyl hydrocarbon having the formula CH2═CHR, wherein R is a saturated aliphatic radical having at least 2 carbon atoms or is a cycloaliphatic radical, in the presence of a catalyst comprising a catalytic aluminum alkyl compound and a catalytic titanium halide compound.
A process for preparing a copolymer comprising copolymerizing olefins comprising a monomeric vinyl hydrocarbon having the formula CH2═CHR wherein R is a saturated aliphatic radical having at least 2 carbon atoms or is a cycloaliphatic radical, in the presence of a catalyst comprising a catalytic aluminum alkyl compound and a catalytic titanium halide compound.
A process for preparing a copolymer comprising copolymerizing (i) an olefin having the formula CH2═CHR wherein R is a saturated aliphatic radical having at least two carbon atoms or is a cycloaliphatic radical with (ii) an olefin without a vinyl group which is ethylene, in the presence of a catalyst comprising a catalytic aluminum alkyl compound and a catalytic titanium halide compound.
