Ws. Yin et al., SILICON SECONDARY CROSS-LINKED IPN BASED ON POLY(METHYL ACRYLATE-CO-ACRYLIC ACID) AND SIO2, Journal of applied polymer science, 64(5), 1997, pp. 903-909
Silicon secondary crosslinked interpenetrating polymer networks (IPNs)
of poly(methyl acrylate-co-acrylic acid) (PMAA) and SiO2 were prepare
d and characterized. The effects of composition, water content, and su
bstrate plate on the phase morphology of the IPNs of PMAA/SiO2 have be
en studied by scanning electron microscopy, and the glass transition t
emperature measured by differential scanning calorimetry. By controlli
ng the synthetic conditions an optically transparent film was obtained
, which shows a remarkably high degree of mixing between the two chemi
cally dissimilar phases. (C) 1997 John Wiley & Sons, Inc.
