This paper describes the isospecific polymerization of 4-methyl-1,3-pentadiene (4-MDP) with high degree of stereocontrol promoted by a new homogeneous C2-symmetric octahedral titanium catalyst. The isotactic polymer have been fully characterized by NMR, FTIR, X-ray diffraction, and thermal analysis. The polymorphic behavior observed in the polymer is analogous to that described for the isotactic polymer obtained in the presence of heterogeneous Ziegler-Natta catalyst.

Abstract
This paper describes the isospecific polymerization of 4-methyl-1,3-pentadiene (4-MDP) with high degree of stereocontrol promoted by a new homogeneous C2-symmetric octahedral titanium catalyst. The isotactic polymer have been fully characterized by NMR, FTIR, X-ray diffraction, and thermal analysis. The polymorphic behavior observed in the polymer is analogous to that described for the isotactic polymer obtained in the presence of heterogeneous Ziegler-Natta catalyst.File in questo prodotto:
