Abstract: Anovel interpenetrating polymer network(IPN)of isotactic polypropylene/poly n-butyl acrylate(PP/PnBA)was prepared by in-situ polymerization of n-butyl acrylate in the pores of matrix polypropylene(PP)microporous membrane.The composite IPNmembrane was characterized by using the methods of FT-IR, polarized light microscope(PLM), SEM, XPS, WASDand stress-strain measurements。It has been found that the PnBAcomposition in the surface of the composite membrane was depedent on the pore number in the surface of the matrix PPmembrane.The structure of the matrix PPmicroporous membrane was preserved in a great extent.Almost all the pores were filled with crosslinked PnBAso that a continuous PnBAphase formed which was interpenetrated with PPphase。The mechanical properties of composite IPNmembrane were improved in some aspects in comparison with the matrix membrane.
