In-Situ Polymerization of UHMWPE Using Bi-Supported Ziegler-Natta Catalyst of MoS2 Oxide/MgCl2 (Ethoxide Type)/TiCl4/TiBA: Study of Thermo-Mechanical Properties of System
The use of UHMWPE has attracted the attention of many researchers and industries. The aim of the present work is to fabricate UHMWPE/MoS2-Oxide nano-composites using in-situ polymerization. For this purpose, modified molybdenum disulfide was used. In order to perform the polymerization, a Ziegler-Natta catalytic system, with MoS2-Oxide and magnesium Ethoxide as support, was used. In order to fa...
متن کاملCoordination (co)polymerization of olefins
Introduction Middle 1950s may be treated as the beginning of the age of plastics – their global production in last 60 years have increased from approx. 1.5 mln to almost 290 mln tons. The dominating position in production and consumption of these materials for many years has been occupied by polyolefins (in Europe 48% from 57 mln tons of plastics) [1]. Forecasters predict that in coming years t...

15 صفحه اولPrecise Active Site Analysis for TiCl3/MgCl2 Ziegler-Natta Model Catalyst Based on Fractionation and Statistical Methods
In heterogeneous Ziegler-Natta catalysts for olefin polymerization, isolation of a single type of active sites is a kind of ambition, which would solve long-standing questions on the relationship between active site and polymer structures. In this paper, polypropylene produced by TiCl3/MgCl2 model catalysts with minimum Ti heterogeneity was analyzed by combined solvent fractionation and the two...
