New di- or oligo-1,2,4-triazolidine-3,5-diones corresponding to the following Formula I: ##STR1## in which R.sup.1 represents a difunctional to pentafunctional organic radical, optionally substituted and/or interrupted by hetero atoms or hetero atom groups and n=a number of from 2 to 5. The compounds of Formula I are obtained by reaction of 0.9 and 1.1 Mole hydrazodicarbonamide or 1,2,4-triazolidine-3,5-dione with 1/n mole of an amine of the formula R.sup.1 (NH.sub.2).sub.n by elimination of ammonia or by reaction of a monosubstituted hydrazodicarbonamide of the formula (H.sub.2 N--CO--NH--NH--CO--NH).sub.n R.sup.1 by elimination of ammonia. R.sup.1 and n have always the same meaning as in Formula I. The di- and oligo-1,2,4-triazolidine-3,5-diones are valuable starting materials for the production of in 1,2-position oxalkylated or glycidyl group containing intermediates for the production of polymers.
根据以下的公式I,直接合成新的di-或oligo-1,2,4-三唑烷-3,5-二酮:##STR1##其中R.sup.1代表一个二功能到五功能的有机基团,可选择性地被杂原子或杂原子基团取代和/或中断,n=2到5。通过将0.9到1.1摩尔的叠氮二羧胺或1,2,4-三唑烷-3,5-二酮与1/n摩尔的式为R.sup.1(NH.sub.2).sub.n的胺反应,通过消除氨气得到公式I的化合物,或者通过消除氨气将式为(H.sub.2 N--CO--NH--NH--CO--NH).sub.n R.sup.1的单取代叠氮二羧胺反应得到。R.sup.1和n在公式I中的含义始终相同。这些di-和oligo-1,2,4-三唑烷-3,5-二酮是用于生产1,2-位置氧乙基化或含有环氧丙基基团的中间体以制备聚合物的有价值的起始原料。
