Phosphazene homopolymers and copolymers having hydroxylated or amino derivatives of carbazole or of naphthalene as substituents.

摘要

Polyphosphazene homopolymers and copolymers containing repetitive units represented by the general formula: <CHEM> in which the substituents X, which can be equal or different, are represented by the following formulas: <CHEM> <CHEM> <CHEM> where R is hydrogen or a C1-C5 alkyl group or an aryl or heterocyclic group, with or without substituents, R' is CH2 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<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 (NPCl2)m in which m can vary from 20 to 50,000, and can be used as photoconductor materials and for other uses.
