摘要：

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 SiO2 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).
