Notes:
A correlative approach is illustrated in which some conformational features of Lewis bases used in Ziegler-Natta heterogeneous catalysts for isotactic poly(propylene) proved to be molecular descriptors strongly correlating with stereoregulating power and polymerization yield. They are both steric and statistical descriptors and have been obtained through the analysis of the entire rotational hypersurface of the considered compounds. The correlative study selected some of their values as necessary conditions for a good stereoregulating effect. Their calculation for new molecules led to the predictive evaluation of new chemical classes as efficient stereoregulating electron donors and to the choice of the most effective ones.
