Silicon secondary crosslinked interpenetrating polymer networks (IPNs) of poly(methyl acrylate‐co‐acrylic acid) (PMAA) and SiO 2 were prepared and characterized. The effects of composition, water content, and substrate plate on the phase morphology of the IPNs of PMAA/SiO 2 have been studied by scanning electron microscopy, and the glass transition temperature measured by differential scanning calorimetry. By controlling the synthetic conditions an optically transparent film was obtained, which shows a remarkably high degree of mixing between the two chemically dissimilar phases. © 1997 John Wiley & Sons, Inc.
