Journal ArticleDOI
Microstructure Distribution of Polypropylenes Obtained in the Presence of Traditional Phthalate/Silane and Novel Diether Donors: A Tool for Understanding the Role of Electron Donors in MgCl2-Supported Ziegler-Natta Catalysts
Giampiero Morini,Enrico Albizzati,Giulio Balbontin,Ines Mingozzi,Maria Carmela Sacchi,Fabrizio Forlini,Incoronata Tritto +6 more
TL;DR: In this paper, three diethers, 2,2-diisobutyl-1,3-dimethoxypropane, 2.2-dicyclopentyl- 1, 3-dimethylpropane and 2.ethyl-2-butyl -1, 3dimethyl-propane have been used as internal donors in MgCl2−TiCl4−diether/AlR3 catalysts for the polymerization of propylene.
Journal ArticleDOI
Effects of Internal and External Donors on the Regio- and Stereoselectivity of Active Species in MgCl2-Supported Catalysts for Propene Polymerization
John C. Chadwick,Giampiero Morini,Giulio Balbontin,Isabella Camurati,Johannes J. R. Heere,Ines Mingozzi,Fabio Testoni +6 more
TL;DR: In this article, the effects of different alkoxysilanes on polymer tacticity and molecular weight distribution are interpreted in terms of lability of donor coordination in the vicinity of active species, a labile as opposed to a stable donor coordination giving rise to a higher proportion of defect-rich sequences in the polymer chain.
Journal ArticleDOI
Syndiospecific styrene polymerization promoted by half-titanocene catalysts : A kinetic investigation providing a closer insight to the active species
TL;DR: In this paper, a first-order kinetics of the monomer in the propagation rate has been determined at 25 °C and at polymerization temperatures higher than 50 °C, the β-H migration from the growing polymer chain to the metal of the active species appears to be the main termination reaction.
Journal ArticleDOI
Aspects of hydrogen activation in propene polymerization using MgCl2/TiCl4/diether catalysts
John C. Chadwick,Giampiero Morini,Enrico Albizzati,Giulio Balbontin,Ines Mingozzi,Antonio Cristofori,Olof Sudmeijer,Gerard M. M. Van Kessel +7 more
TL;DR: In this paper, the chain-end distribution of poly(propylenes) prepared using the highly active catalyst system MgCl 2 /TiCl 4 /diether -AlEt 3 has revealed particularly high proportions of butyl chain-ends in polymers prepared at relatively low hydrogen pressures.
Journal ArticleDOI
Propene polymerization with MgCl2‐supported catalysts: effects of using a diether as external donor
John C. Chadwick,Giampiero Morini,Giulio Balbontin,Ines Mingozzi,Enrico Albizzati,Olof Sudmeijer +5 more
TL;DR: In this paper, NMR analysis of poly(propylene) fractions of different tacticity, obtained using a catalyst system of type MgCl 2 /TiCl 4 /diisobutyl phthalate - AlEt 3 - diether, has provided further evidence that the active species in this system are similar to those in which the ether is used as internal rather than external donor.
