Abstract
Diolefines are polymerized in the presence of a catalyst obtained by reacting an organometallic compound of a metal of Group I, II or III of the Periodic Table with a compound of a transition metal of Group IV, V or VI in which the metal is bound to an organic radical through an oxygen atom. The first compound is preferably triethyl aluminium, the second an alkoxide or acetylacetonate of titanium, vanadium, chromium or molybdenum which is preferably soluble in any solvent present. The two components may be dissolved separately in a hydrocarbon and then mixed. Specifications 810,023 and 834,554 are referred to.ALSO:Linear polymers are prepared from conjugated diolefins having at least one vinyl group by polymerizing in the presence of a catalyst obtained by reacting an organo-metallic compound of a metal of Group I, II or III of the Periodic Table with a compound of a transition metal of Group IV, V or VI in which the metal is bound to an organic radical through an oxygen atom. The transition metal compound is preferably soluble in any solvent present and may be an alkoxide or acetyl-acetonate of titanium, chromium, vanadium or molybdenum. The organo-metallic compound may be triethyl aluminium. The polymerization is preferably carried out in a hydrocarbon solvent and the catalyst is prepared by suspending or dissolving the two components in separate portions of the hydrocarbon and then mixing. The monomer may be added to the suspension or solution of the organo-metallic compound before adding the transition metal compound or may be added to the composite catalyst. Temperatures of -80 DEG to 150 DEG C. may be used. Monomers include butadiene and isoprene. Butadiene yields a mixture of an amorphous and a crystalline polymer which may be separated by dissolving the latter in solvents such as acetone, ether, heptane and toluene. The butadiene polymer has 1,2-enchainment and the isoprene polymer, which is amorphous, 3,4-enchainment. The polymers may be vulcanized. The crystalline polymers can be extruded into filaments and moulded or calendered at temperatures slightly below the melting temperature to obtain sheets with a plane orientation. Oriented films can be obtained by cold-drawing in two directions unoriented sheets obtained by moulding or calendering at above the melting temperature. The amorphous polymers are elastomeric. Specifications 810,023 and 834,554 are referred to.
