| titleOfInvention | Polymerization of olefinically unsaturated hydro-carbons and catalyst therefor |
| abstract | Olefinically unsaturated compounds are polymerized in the presence of, as catalyst components, at least one organo-metallic reducing agent and at least one vanadium compound of formula <FORM:1005050/C3/1> where R1 and R2 are the same or different substituted or unsubstituted hydrocarbon radicals and R3 and R4 each is hydrogen or a substituted or unsubstituted hydrocarbon radical. Suitable substituents include hydroxy, alkoxy, oxygen atoms of carbonyl groups, carboxy, carboxylic ester, amino, mercapto, sulpho and halogen. The radicals may be saturated or unsaturated aliphatic or cycloaliphatic, or aromatic. Suitable organo-metallic compounds include those of metals of the first to fourth groups, particularly alluminium alkyls and aluminium alkyl halides. The catalyst may be prepared by mixing the components, optionally in the presence of a solid carrier. Ratios of Al to V may be between 1 : 1 and 20 : 1. Polymerization is preferably effected in a hydrocarbon diluent. Temperatures of - 20 DEG to + 150 DEG C. may be used and pressures of 1 to 50 atmospheres. In an example, ethylene and propylene are copolymerized in the presence of a catalyst prepared from VO[OCH = CH-CO-C(CH3)3]2, AlC2H5Cl2 and Al(C2H5)2Cl. Reference is also made to the copolymerization of ethylene and/or propylene with butene-1 or dodecene-1, and to polymerization of butadiene.ALSO:The invention comprises <FORM:1005050/C2/1> where R1 and R2 are the same or different substituted or unsubstituted hydrocarbon radicals and R3 and R4 each in hydrogen or a substituted or unsubstituted hydrocarbon radical. Suitable substituents include hydroxy, alkoxy, oxygen atoms of carbonyl groups, carboxy, carboxylic ester, amino, mercapto, sulpho and halogen. They are prepared by reacting a vanadium and/or vanadyl water-soluble salt in in aqueous medium with a water-soluble salt of the enol form of a ketoaldehyde R1R2R3CCOCR4 =CHOH or by reacting in a hydrocarbon medium, vanadium hydroxide and a ketoaldehyde R1R2R3CCOCHR4CHO, preferably with azeotropic distillation of water formed. The products are used in polymerization catalysts.ALSO:Catalyst compositions for polymerizing olefinic compounds comprise at least one organometallic reducing agent and at least one vanadium compound of formula <FORM:1005050/B1-B2/1> where R1 and R2 are the same or different substituted or unsubstituted hydrocarbon radicals and R3 and R4 each is hydrogen or a substituted or unsubstituted hydrocarbon radical. The organometallic compound may be derived from a metal of the first to fourth groups, particularly aluminium alkyls and aluminium alkyl halides. In an example, a mixture of VO[OCH=CH-CO-C(CH3)3]2, AlC2H5Cl2 and Al(C2H5)2Cl is used. |
