Zusammenfassung: | A polyimide oligomer and a preparation method therefor, and a cured product having low-dielectric properties prepared therefrom. The polyimide oligomer has a structure as represented by formula (I) or formula (II), and the symbols in formula (I) and formula (II) are as defined in the description. Therefore, a dimer diamine is used to match a specific monomer and a ratio is adjusted, so as to prepare a free-radical-curable polyimide oligomer; and same has good thermal properties and excellent low-dielectric properties after being cured, so as to be used in the industry of high-frequency circuit boards.
L'invention concerne un oligomère de polyimide et son procédé de préparation, ainsi qu'un produit durci ayant des propriétés faiblement diélectriques préparées à partir de celui-ci. L'oligomère de polyimide a une structure telle que représentée par la formule (I) ou la formule (II), et les symboles dans la formule (I) et la formule (II) sont tels que définis dans la description. Par conséquent, une diamine dimèr |
