Abstract

Inventia prezinta un procedeu de fabricare a unor materiale electroizolante pe baza de rasini poliimidice termoreactive de tip bis-maleimidic. Reactia dintre anhidrida maleica si amina aromata are loc în gamabutirolactona si solventi fenolici, cum ar fi bis-fenol A, rasina fenolica novolac. Rasina fenolica este reactionata la echivalenta cu rasina epoxidica. Cu lacul de impregnare astfel obtinut, se obtin materiale stretificate pe baza de tesaturi de sticla.
