Abstract
The cyclic phosphazenes N3P3F6(CMe3), N3P3F6Ph, non-geffi-N3P3Cl4Me2 non-gem- N3P3Cl4Et2, (NPClMe)3, and (NPClMe)4 have been polymerized to macromolecules of formula [(NPF2)2-NPFR]n, [NPC12(NPClR)2]n, and (NPClR)n. Species (NPClMe)3 and (NPClEt)3 were copolymerized with (NPCl2)3 to yield polymers of type [(NPCl2)x(NPClR)y]n. The halogen atoms in the high polymers were replaced by trifluoroethoxy groups to yield hydrolytically stable derivatives. The influence of the alkyl or aryl groups on the properties of the polymers is described. The new polymers are elastomers, with glass transition temperatures in the -40 to -60 °C range.
