Higher aluminum trialkyls and magnesium aluminum alkyls as components of zioegler–natta catalysts

摘要

AbstractMagnesium aluminum alkyls containing higher (C4–C10) radical swere studied as components of Ziegler–Natta catalysts in styrene polymerization. The effects of alkyl radical length and MgR2contents in the components mentioned on the degree of TiCl4reduction and sterospecific activity of the catalysts were investigated. The components studied exdhibited high reducing (for TiCl4) and catalytic a tivities. Moleculear weight of the synthesized isotactic polystyrene was abnormally h
