Stereoselective 1-3-Butadiene Polymerization Using New Titanium Chelates
Ternary titanium chelates Ti-x(RCOO-)(y)(C16H11O6-)(z) (R = H, CH3, CH3CH2) combined with AlEt2Cl selectively polymerise 1,3-butadiene giving >95% cis-1-4-polybutadiene. The stereoselectivity, activity and oligomer contents are dependent on reaction temperature and Al/Ti ratio.
