摘要： A number of new poly(organophosphazenes) have been synthesized which bear 2-butenoxy or 4-allyloxyphenylphenoxy side groups. Co-substituent groups included trifluoroethoxy, phenoxy, or benzyloxyphenoxy groups. Species with 4-allyloxyphenylphenoxy units underwent Si--H coupling to linear silanes or siloxanes to extend the side groups and form hybrid phosphazene/organosilicon polymers. A number of these polymers are rubbery elastomers which are readily cross-linked by heat or light. Seven of the mixed-substituent, cross-linked polymers were incorporated into interpenetrating polymer networks (IPN's) with polystyrene, poly(methyl methacrylate), polyacrylonitrile, poly(acrylic acid) and poly(dimethylsiloxane). The phase compatibility characteristics of the IPN's were assessed by DSC, TEM, FT-IR spectroscopy, and 1H and 31P NMR spectroscopy data.
