Abstract

Inorganic clay was investigated as a compatibilizer for immiscible poly(propylene)/polystyrene blends. A substantial decrease in the number of polystyrene particles was seen after adding small amounts of an organically treated clay (2–5 wt.‐%) to the blends. A possible mechanism for this kind of compatibilization is discussed, but these unique and completely new findings need further verification.

## Abstract In this work, typical ternary blends of three versatile polymers—polyamide 6, a propylene–ethylene copolymer (__co__‐PP), and polystyrene—were studied. As a compatibilizer, __co__‐PP with randomly dispersed minor ethylene units was multimonomer‐melt‐grafted in the presence of maleic anh

## Abstract **Summary:** Propylene was copolymerized with 10‐undecen‐1‐ol using dimethylsilanylbis(2‐methyl‐4‐phenyl‐1‐indenyl)zirconium dichloride as catalyst and MAO and TIBA as cocatalysts. Comonomer incorporations from 0.1 to 0.9 mol‐% (0.5 to 3.6 wt.‐%) were obtained. These hydroxyl functional
