✦ Synopsis

Microporous polypropylene fibers were prepared by stretching polypropylene fibers containing CaC0, filler. The properties of the resultant fibers are controllable by adjusting the filler content and the stretching ratio. Also, it is elucidated that the fibers have a fine texture of polypropylene fibrils, in which the filler particles are dispersed. Furthermore, the CaCO, filler was removed by treating the fibers with an HC1-CH30H solution, and their properties were also investigated.

Microporous sheets were prepared by biaxially stretching composite nonporous sheets composed of microspherical polymethylsilsesquioxane particles encased in polypropylene. The structural and physical property studies of the sheets obtained thereby show that the porosity, pore-size distribution, and
