For the polymerization of butadiene in hexane on the catalyst system of neodymium neodecanoate / DIBAH / hexachloro-p-xylene, modified by methylaluminoxane, determined distributions of polymerization sites as function of their kinetic activity. Found that the catalyst system contains at least four types of polymerization sites, productivity of which depends on the ratio Cl / Nd.
