ABSTRACT:
Catalyst for production of polyolefins of improved morphology comprises (A) organometallic promoter and (B) product obtained by contacting (1) at least one oxygenated compound of phosphorus with (2) catalytic complex comprising an intimate association of at least one reduced Group IVB-VB metal halide, at least one divalent metal halide and at least one aluminum compound. Oxygenated phosphorus compound is used in an amount effective to improve polymer morphology without substantial adverse effects on other catalytic properties.
