摘要：

It was shown that the polymerization of butadiene and isoprene initiated by a preformed catalytic system Nd(OCOR)3-i-Bu3Al yields polymers containing up to 80% cis-1,4 units rather than trans polymers. The effect of stereospecificity inversion for the examined system is apparently related to reactions between components which lead to the formation of compounds with Al-O-Al and Al-O-C bonds. The presence of these groups was proved by IR spectroscopy.
