Process for the production of polycondensation products of aromatic diazonium compounds

Abstract

Abstract 1. A PROCESS FOR THE PREPARATION OF A POLYCONDENSATION PRODUCT OF AN AROMATIC DIAZONIUM COMPOUND WHICH COMPRISES REACTING IN THE ABSENCE OF ADDED FORMALDEHYDE AT LEAAST ONE A-N2X COMPOUND AND AT LEAST ONE B1 COMPOUND OF THE FORMULA E(-CHRA-ORB)M IN WHICH A-N2X IS A RAICAL OF A COMPOUND SELECTED FROM THE GROUP CONSISTING OF A COMPOUND OF THE FRMULA (R1-R2)P-R2-N2-X AND (-Y-R1''-)>R2-N2-X WHEREIN R1 IS A PHENYL OR NAPHTHYL GROUP R''1 IS A PHENYLENE OR NAPHTHYLENE GROUP R2 IS A PHENYLENE GROUP R3 IS A SINGLE BOND OR ONE OF THE GROUPS -(CH2)Q-NR4-O-(CH2)R-NR4-S-(CH2)R-NR4-S-CH2-CO-NR4-O-R5-O-O-O- OR -CO-NR4THE LEFT-HAND FREE VALENCE OF THE SPECIFFIED GROUPS IS ATTACHED TO R1 AND THE RIGHT-HAND FREE VALENCE IS ATTACHED TO R2, WHEREIN Q IS A NUMBER FROM 0 TO 5 R IS A NUMBER FROM 2 TO 5 R4 IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN ALKYL WITH 1 TO 5 CARBON ATOMS, ARALKYL WITH 7 TO 12 CABON ATOMS, AND ARYL WITH 6 TO 12 CARBON AOMS, R5 IS AN ARYLENE GROUP HAVING 6 TO 12 CARBON ATOMS Y IS ONE OF THE GROUPS -NH-, AND -OX IS AN ANION P IS A NUMBER FROM 1 TO 3 E IS A RAICAL OBTAINED BY SPLITTING OFF OF M H ATOMS FROM A COMPOUND FROM THE GROUP CONSISTING OF AROGROUGROUP SELECTED FROM THE GROUP CONSISTING OF AROMATIC AMINES, PHENOLS, THIOPENOLS, PHENOL ETHERS, AROMATIC THIOETHERS, AROMATIC HETEROCYCLIC COMPOUNDS, AROMATIC HYDROCARBONS AND ORGAIC ACID AMIDES, RA IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND PHENYL, RB IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND ALKYL CNH2N+1CO- WHEREIN N IS FROM 0 TO 3 AND A PHENYL GROUP, AND M IS AN INTEGER FROM 1 TO 10 IN A STRONG ACIDIC CONDENSATION MEDIUM AND UNDER CONDENSATION CONDITIONS SUFFICIENT TO PRODUCE A POLYCONDENSATION PRODUCT OF AN AROMATIC DIAZONIUM COMPOUND CONTAINING, ON THE AVERAGE, ABOUT 0.1 TO 50 B1 UNITS PER UNIT OF A-N2X.
