Microporous polypropylene sheets are prepared by biaxially stretching polypropylene sheets containing CaCO 3 filler. Here, the stretching ratio is one of the most important factors in the preparative process, and removing the CaCO 3 filler also affects the sheet properties. Their effects were studied in relation to the properties and the structure of the microporous polypropylene sheets. © 1998 John Wiley & Sons, Inc. J Appl Polym Sci 68: 1543–1553, 1998
