抄録

Aromatic polyimides are considered to be a class of high performance polymers, and they have found a wide range of applications in electronics, aerospace and other industries. They were developed in the 1960s owing to intensive research on heat-resistant polymer. Polyimides in various forms (film, composite matrix, adhesive, plate, etc) were developed now. However, the particle of polyimides were studied only a little until the latter half of the 1990's. Even if polyimides are processed to the particle shape, the particles can be expected to show excellent features. Then, we zealously examined the preparative procedure of polyimide particles, and established the following two methods. (1) Several kinds of polyamic acid particles were prepared using diamines and anhydrous tetracarboxylic acids through precipitation polymerization in organic solvent under ultrasonic irradiation. These polyamic acid particles were heated by about 140-200 °C, and the polyimide particles were obtained. The polyimide particles of an arbitrary size were able to be prepared by this method within the range of submicron order. Moreover, it was also possible to support functional groups to surfaces of the polyimide particles. (2) Polyimide particles of micron order were obtained by heating polyamic acid varnish at about 140-200 °C that induced the thermal imidization of polyamic acids in aproticpolarsolvent. Similarly, it was also possible to support functional groups to surfaces of the polyimide particles by this method.
