Copolymerization studies of vinyl chloride and vinyl acetate with ethylene using a transition-metal catalyst.
Since the advent of Ziegler-Natta polymerization of ethylene, attempts have been made to extend coordination polymerization to commercially important monomers with polar functionality. In this study we examined the copolymerization of perdeuterated vinyl chloride (VC) and perdeuterated vinyl acetate (VA) with ethylene using a tridentate Fe(II) dichloride pyridine diimine metal catalyst. The res...

متن کاملReactions of Amino-imino-boranes with Transition Metal Halides and Substituted Transition Metal Halides
The aminoiminoborane tmp-B=NCMe3 (1) adds to TiBr4 or ZrCL in a 1:1 ratio while PdCh adds 1 in a 1:2 ratio. In these new compounds the NBN unit is almost linear and the configuration corresponds to an allene. On the other hand 1 and Ti(OR)4 compounds and Ti(NMe2)4 give N metallated diaminoboranes tmp-B(X)-NCMe3EX3 (X = OR, NMe2). Mixed compounds Ti(OR)3_„X„ lead to diaminoboranes with BOR group...
متن کاملDetermination of kinetic parameters for ethylene polymerization (with and without hydrogen) by Ziegler-Natta catalyst.
In this study, slurry polymerization kinetics of ethylene with TiCl4/Mg(OEt)2/AlR3 Ziegler-Natta catalysts in various conditions using the model of sum square error (SSE) (method I) and model of least square error (LSE) (Method II) was investigated. For this purpose the molecular weight distributions of the samples were deconvoluted to the minimum number of Flor...
