Sol–gel reaction of tetraethoxysilane was carried out in molten polypropylene with the aid of an extruder. The resultant composites were used to mold sheets containing finely dispersed SiO 2 particles. These sheets were biaxially stretched to prepare microporous films, of which some properties were estimated (pore size, porosity, specific surface area, and gas permeability). © 1999 John Wiley & Sons, Inc.
