Title:

POLYPROPYLENE EXTRUSION COATING RESINS AND PROCESS FOR THE PRODUCTION THEREOF

Document Type and Number:

WIPO Patent Application WO1993009150

Kind Code:

A3

Abstract:

Novel polypropylene compositions comprising up to 100 mol % propylene having a melt flow rate of 20 to 150 g/min at 230 DEG C and a total xylene solubles content between 4 and 35 wt. % are disclosed. In addition, a process for the production of the polypropylene composition in gas phase with particular aluminum/titanium ratios and cocatalyst/electron donor ratios is disclosed as well as a process for extrusion coating the polypropylene compositions and the laminated articles prepared thereby.
