Cis-polyisoprene prodn. - by soln. polymerisation of isoprene! with a reaction prod. of titanium tetra:chloride and organo aluminium cpd. as stereoregular catalyst

Cis-polyisoprene is made by polymerising isoprene in an polar hydrocarbon solvent medium at 0-60 degrees C in the presence of 0.2 - 0.7 pts. wt. (per 100 pts. wt. isoprene) of a catalyst consisting of a 1:1.5 to 1:1.1 (mol) reaction prod. of TiCl4 and an inter cyclic organoaluminium cpd. of formula...
