Brintzinger and Fischer [29].
The chiral metallocene-based catalysts are characterized by a defined active
center, forming a sound basis for establishing relationships between the molecular
structure of the catalyst and the microstructure of the resulting polymer. Catalyst–
polymer correlations are addressed using approaches ranging from symmetry-based
rules [30, 31] (as illustrated in Fig. 18) to more elaborate computational approaches
that attempt to accurately predict the polymer microstructure (see below).
