Electrophotographic uses of selenium containing polymers
Abstract
Abstract THIS INVENTION RELATES TO ORGANIC DISELENIDES AND POLYSELENIDES AMONG WHICH ARE CYCLIC COMPOUNDS REPRESENTED BY THE FORMULA: R<(-SE-(X)N-SE-) WHEREIN R'' IS SELECTED FROM DIVALENT HYDROCARBYLENE RADICALS OF 5 TO 20 CARBON ATOMS, DIVALENT HETEROCYCLIC, ALICYCLIC AND AROMATIC RADICALS HAVING FROM 3 TO 50 CARBON ATOMS, N IS A POSITIVE INTEGER AND X IS THE RADICAL -SE-R-SE-; LINEAR POLYMERS HAVING A REPEATING UNIT REPRESENTED BY THE FORMULA: -SE-A-SE- WHEREIN A IS SELECTED FROM DIVALENT ALKYLENE RADICALS HAVING FROM 9 TO 20 CARBON ATOMS, DIVALENT AROMATIC RADICALS FROM 6 TO 50 CARBON ATOMS AND DIVALENT HETEROCYCLIC RADICALS AND POLYMERS HAVING A REPEATING UNIT REPRESENTED BY THE FORMULA: -(B-SE)B- WHEREIN B IS SELECTED FROM THE GROUP CONSISTING OF DIVALENT HYDROCARBYLENE RADICALS AND DIVALENT HETEROCYCLIC RADICALS, A IS A POSITIVE INTEGER OF AT LEAST 3 AND B IS A POSITIVE INTEGER GREATER THAN 1. THIS INVENTION ALSO RELATES TO THE USE OF THESE COMPOUNDS IN THE PRODUCTION OF ELECTROPHOTOGRAPHIC PLATES.
