The polyamideimide resin composition of the present invention has high heat resistance and high bond strength and can achieve sufficient adhesion at lower temperature, for example, 160 to 180° C. Thus, the resin composition of the present invention is suitable for use in bonding circuit boards and IC members.
摘要:
The present invention provides a polyimide resin formed by polycondensating a dianhydride monomer including at least a dianhydride monomer represented by formula (I) and a diamine monomer to form a polyamic acid resin, and then cyclodehydrating the polyamic acid. Through using the dianhydride monomer of formula (I) as the polymerizing unit, a biphenyl moiety is introduced into the main chain of polyimide resin, such that the resulting polyimide resin has lower moisture absorption and smaller thermal expansion coefficient, as well as satisfactory heat resistance and dimensional stability.

摘要:
The present invention provides a polyimide resin, which is prepared by epolycondensing a dianhydride monomer including at least a dianhydride represented by formula (I) wherein R is O or O(CH2)nO, n is an integer of 1 to 2 and a diamine monomer represented by formula (II) H2N—Ar—NH2 (II) wherein Ar is defined as in the text then imidizing the resulting polyamic acid resin to form a polyimide resin. Through using the dianhydride represented by formula (I) as the polymerizing unit, a biphenyl moiety and an ester moiety are introduced into the main chain of the polyimide resin, such that the resulting polyimide resin has lower moisture absorption and smaller linear thermal expansion coefficient and therefore have satisfactory heat resistance and dimensional stability, in addition, become more soluble in organic solvents.
