Mixtures of isomeric alkylthiated mononuclear aromatic amines comprising in the range of about 30 to about 70 mole percent of (i) at least one 3,5-di(alkyl-thio)-2,6-diamino-1-alkylbenzene and in the range of about 30 to about 70 mole percent of at least one 3,5-di(alkylthio)-2,4-diamino-1-alkylbenzene, such mixture containing at least about 90 mole percent of (i) and (ii), and optionally containing up to 10 mole percent of one or more isomers of (i) and/or (ii). An alkyl group may be present as a substituent in lieu of a hydrogen atom in the remaining ring position. These mixtures are useful as curatives or extenders in processes for making polyurethanes, polyurethane-ureas, and polyureas.

Смеси изомерного alkylthiated одноядерные ароматичные амины состоя из in the range of about 30 до около 70 процентов моли (i) по крайней мере одного 3,5-di(alkyl-thio)-2,6-diamino-1-alkylbenzene и in the range of about 30 до около 70 процентов моли по крайней мере одного 3,5-di(alkylthio)-2,4-diamino-1-alkylbenzene, такой смеси содержа по крайней мере около 90 процентов моли (i) и (ii), и опционно содержа up to 10 процентов моли one or more изомеров (i) and/or (ii). Алкиловая группа может присутствовать как заместитель in lieu of атом водопода в остальном положении кольца. Эти смеси полезны как curatives или разбиватели в процессах для делать полиуретаны, полиуретан-moceviny, и polyureas.
