Abstract
In the ion-coordination polymerization of dienes catalyzed by lanthanide sy stems, the kinetic-activity distribution of active sites were determined us ing the molecular mass distribution curves obtained by the Tikhonov regular ization method. The polymodal pattern of distributions suggests the presenc e of several yupes of active centers, which change their kinetic activity d uring polymerization.
