Curable mixtures comprising a polyepoxide compound having on average more than one epoxide group per molecule and a 1,3-diaminopropane of the formula ##STR1## wherein R.sup.1 denotes hydrogen and R.sup.1, R.sup.2, R.sup.3 and R.sup.4 each denote an alkyl having 1 to 12 C atoms, a phenyl or a heterocyclic 5-membered or 6-membered radical, or wherein R.sup.1 and R.sup.2 together with the C atom in the .alpha.-position of the propylenediamine from a substituted or unsubstituted aliphatic 5-membered or 6-membered ring having at most 12 C atoms and R.sup.3 and R.sup.4 together with the two C atoms in the .alpha.-position and the .beta.-position of the propylenediamine form a substituted or unsubstituted aliphatic or N-heterocyclic 5-membered or 6-membered ring having at most 12 C atoms, said mixtures containing 0.5 to 1.5 equivalents of active hydrogen atoms, bonded to nitrogen, in the 1,3-diaminopropane per 1 equivalent of epoxide groups in the epoxide compound. The curable mixtures are valuable casting resins and adhesives and are suitable for the preparation of storable B-stage resins.
可治疗混合物包括平均每分子具有多于一个环氧基团的聚环氧化合物和式为##STR1##的1,3-二氨基丙烷,其中R.sup.1表示氢,R.sup.1,R.sup.2,R.sup.3和R.sup.4各自表示具有1到12个碳原子的烷基,苯基或杂环5元或6元基,或者其中R.sup.1和R.sup.2与丙二胺的α-位碳原子形成具有最多12个碳原子的取代或未取代脂肪族5元或6元环,R.sup.3和R.sup.4与丙二胺的α-位和β-位碳原子形成具有最多12个碳原子的取代或未取代脂肪族或N-杂环5元或6元环,所述混合物含有每个环氧化合物中的1当量环氧基团对应的0.5到1.5当量与氮相键合的活性氢原子的1,3-二氨基丙烷。这些可固化混合物是有价值的铸造树脂和粘合剂,适用于制备可储存的B级树脂。
