Microporous polypropylene sheets were prepared as follows. First, polypropylene pellet‐containing CaCO 3 filler was extruded to prepare base sheets, which were then biaxially stretched. The draft effect at the extrusion process was studied in relation to some properties of the resultant microporous polypropylene sheets. © 1996 John Wiley & Sons, Inc.
