Kinetic regularities of piperylene polymerization with NdClcx3TBP-Al(i-C4H9)3 catalytic system
Description
On the basis of experimental data and quantum-chemical calculations of the electronic structure of the models of active centers it is shown that the mechanism of kinetic anti-stereocontrol of the polymer microstructure is realized in polymerization of piperylene with NdClcx3TBP-Al(i-C4H9)3 catalytic system. Upon insertion of a diene into the chain, the forming anti-form of the terminal unit has time to isomerize to a thermodynamically more advantageous syn-form. 8 refs., 1 fig., 2 tabs
