| titleOfInvention | MEANS OF THE BASE OF HIGH-MOLECULATED, CIRCULATED, N, N'-DIFENYL-P-PHENYLENEDIAMINES, THE METHOD OF ITS PREPARATION AND POLYMERIC COMPOSITION WITH ITS CONTENT |
| abstract | Higher molecular, ring-substituted N, N'-diphenyl-p-phenylenediamines of formula (I) wherein R 1 is hydrogen, methyl or N-phenylamino, R 2 is hydrogen, methyl, N-phenylamino or hydroxy, are described. integers from 0 to 2, and preparing them by reacting hydroquinone with 1 to 2.2 mol times the N-phenyl-p-phenylenediamine of formula (II) and / or 2 to 2.5 mol times of aromatic amines, consisting of various molar ratios of aniline , o-toluidine, optionally p-toluidine or mixed toluidines, further mixed xylidines or even individual xylidine and from 1 to 99% of N-phenyl-p-phenylenediamine of formula (II), wherein the condensation takes place at a temperature of 175 to 320 ° C from 3 to 18 h in the presence of a condensation catalyst to precipitate the reaction water. For stabilization, the composition is added in an amount of 0.05 to 5.0% by weight to the polymer substrate, which may be a synthetic rubber hydrocarbon latex or a natural and / or synthetic rubber based vulcanizate. |
