ABSTRACT:
2,2'-Dichloro-6,6'-diethylmethylene-bis-aniline or mixtures thereof with compounds of the formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are the same or different and are straight-chained or branched alkyl radicals having 2 to 4 C atoms, or R.sub.1 and/or R.sub.3 are chlorine and the remaining R's have the above-mentioned significance, as chain-extension means or cross-linkage means for polyurethanes or epoxide resins. Process for the production of 2,2'-dichloro-6,6'-diethylmethylene-bis-aniline or such mixtures. 2-ethyl-6-chloroaniline is condensed with itself or an aniline having the formula: ##STR2## wherein R.sub.5 and R.sub.6 are the same or different and are straight-chained or branched having 2 to 4 C atoms, with the proviso that R.sub.5 can also be chlorine, in acidic medium with formaldehyde or compounds which form formaldehyde. The compounds in the mixture can be condensation products of two molecules of such aniline derivatives.
