Abstract

Procedure for preparing a photoconductor from a polymeric condensation product of formaldehyde, paraformaldehyde and optionally at least one carbocyclic polynuclear aromatic compound, especially for electrophotographic layers in the mixture with activators and optionally with binders and other additives by introducing the components in a solvent and condensate in the presence of a condensation catalyst with temperatures between 80 and 100ºC, polycondensate precipitation, absorption, purification and drying, characterized in that dioxane is used as solvent and perchloric acid as condensation catalyst, the precipitation of the polycondensate is carried out, consisting of periodic uncrosslinked units of the formulas: **(See formula)** where X1 and X2 are the same or different and signify hydrogen, alkyl or alkoxy of 1 to 4 carbon atoms each, halogen preferably chlorine or bromine, X3 and X4 are the same or different and the alkyl or alkoxy of 1 to 4 carbon atoms each, halogen, preferably chlorine or bromine and n is an integer between 6 and 10 approximately, the polycondensate of which may also be co-condensed with biantrile units, by instilling the solution in a lower aliphatic alcohol and the purification by collecting the polycondensate in tetrahydrofuran and precipitation in a lower alcohol. .
