Rd. Chapman et al., POLYALKOXYPHOSPHAZENES BY ROOM-TEMPERATURE POLYMERIZATION OF AN ELECTRONEGATIVE PHOSPHORANIMINE MONOMER, Journal of inorganic and organometallic polymers, 6(3), 1996, pp. 267-275
A new electronegative alkoxyphosphazene monomer, -dinitropropoxy)N-(tr
imethylsilyl)phosphoranimine, has been prepared. The anionic polymeriz
ation of this monomer occurs even at room temperature, in contrast to
that of previous trialkoxy-N-(trimethylsilyl)phosphoranimines, which r
equire elevated temperatures for efficient polymerization. The new pol
ymerizations occur via catalysis by tetra-n-butylammonium fluoride or
even by adventitious moisture.
