    摘要： Novel phthalic acid derivatives, especially phthalic anhydrides, which are substituted by alkenylamino groups, and a process for their preparation are described. The novel phthalic acid derivatives are valuable intermediates for the preparation of corresponding esters, ester-amides or imides, which, in turn, are used in hot-curable mixtures which are stable on storage and have improved processing characteristics, in particular a prolonged pot life, for the production of mouldings of various types. Phthalic anhydrides substituted by alkenylamino groups, according to the invention, are also suitable as curing agents for epoxide resins. Products or materials cured therewith are distinguished by good mechanical and/or electrical properties.
