Effect of external donor and prepolymerization on the performance of Ziegler-Natta catalysts in propylene polymerization.

Revista Técnica de la Facultad de Ingeniería, 2010
In a batch-wise operated autoclave reactor, liquid propylene was polymerized using two Ziegler-Natta catalytic systems: TiCl4/MgCl2/phthalate (A) and TiCl4/MgCl2/1,3-diether (B). The influence of cyclohexylmethyldimethoxysilane, used as external donor (
