Novel phthalic acid diesters or ester-amides substituted by alkenylamino groups, processes for their preparation and hot-curable mixtures which are stable on storage and contain at least one phthalic acid diester according to the invention or a phthalic acid ester-amide according to the invention and a polyimide which has at least two groupings containing a C.dbd.C double bond are described. These hot-curable mixtures which are stable on storage are distinguished by improved processing characteristics, in particular a prolonged pot life, and are suitable for the production of various mouldings and especially also for the production of complicated castings.
                            本发明涉及一种新型的
邻苯二甲酸二酯或酯酰胺,其被烯基
氨基基团取代,以及其制备方法。本发明还涉及一种热固性混合物,其在储存期间稳定,并且包含本发明中至少一种
邻苯二甲酸二酯或酯酰胺和至少含有两个C.dbd.C双键基团的聚
酰亚胺。这些在储存期间稳定的热固性混合物具有改善的加工特性,特别是较长的搅拌时间,适用于制造各种模具,尤其是复杂的铸件的生产。
