Determination of a Cumulative Distribution Function of Kinetic Activity of Lanthanide Ion-coordination Catalytic Systems Used for Diene Polymerization
Source abstract
Abstract
Abstract From the experimentally obtained of curves 1,4-cis-polybutadiene molecular weight-distribution the cumulative distribution functions on kinetic activity of polymerization centers of NdCl33L-Al(i-C4H9)3 catalytic system are obtained by the Tikhonov regularization procedure. At least four types of active sites distinguished by kinetic activity are detected. The influence of polymerization condition and concentration of the components of the polymerization system on a modification of their activity is shown.
