Prezenta inventie se refera la un procedeu pentru sinteza unei poliesterimide nesaturate, utilizabila la fabricarea lacurilor electroizolante. Procedeu se desfasoara în doua trepte, si anume: în prima treapta se efectueaza reactia dintre trimetilica, diaminodifenil-metan si propilenglicol, dupa care, în treapta urmatoare, diolul având grupe imidice si esterice se supune poliesterificarii.The present invention relates to a process for the synthesis of an unsaturated polyesterimide, useful in the manufacture of electrically insulating lakes. The process is carried out in two steps, namely: in the first step, the reaction is carried out between trimethylethyl, diaminodiphenyl-methane and propylene glycol, after which, in the next step, the diol having imidic and ester groups undergoes polyesterification.
