ABSTRACT:
Polyphosphazene homopolymers and copolymers containing repetitive units represented by the general formula: ##STR1## in which the substituents X, which can be equal or different, are represented by the following formulas: ##STR2## where R is hydrogen or a C.sub.1 -C.sub.5 alkyl group or an aryl or heterocyclic group, with or without substituents, R' is CH.sub.2 or an aryl or heterocyclic group, with or without substituents, n is zero or a whole number variable from 1 to 5 and Y is hydrogen or a halogen or a methyl, nitroso or nitro group; the substituents X.sup.1 are groups equal to X or halogen, or alkoxy, aryloxy, amino or mercapto groups, either substituted or unsubstituted, or a mixture thereof; the sum (w+y+z) has a value varying from 20 to 50,000.
The polymers of the present invention are prepared from the corresponding poly(dichlorophosphazenes) of general formula (NPCl.sub.2).sub.m in which m can vary from 20 to 50,000, and can be used as photoconductor materials and for other uses.
