Abstract
The functions of center distribution are constructed according to their polymerization kinetic activity for butadiene polymerization in hexane using neodymium neodecanoate/diisobutylaluminum/hexachloro-p-xylene modified with methylaluminoxane (MAO) as a catalytic system. The catalytic system was found to be heterogeneous and contain at least four types of polymerization centers, and the productivity of the catalyst system depends on the ratio of MAO/Nd and Cl/Nd.
