新規な酸二無水物に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a novel acid dianhydride useful as a raw material for heat-resistant resins such as polyimide.
ポリイミドは種々の有機ポリマーの中でも耐熱性に優れ

く用いられている。特に最近では、単に耐熱性に優れて

ことが望まれている。Polyimide has excellent heat resistance among various organic polymers, so it is widely used in fields ranging from space and aviation to electronic communications. Particularly recently, it has been desired not only to have excellent heat resistance but also to have various performances depending on the application.

。しかし、これらの性能を充分に満足するポリイミドは
現在のところ得られていない。For example, base films for flexible printed circuit boards, carrier tapes for TAB (tape automated bonding), and resins for laminates are desired to have a low coefficient of thermal expansion, a low dielectric constant, and low hygroscopicity. However, a polyimide that satisfactorily satisfies these properties has not yet been obtained.

れるが、構造コストがかさむこと、酸無水物の反応性が
低下することが予想され好ましくない。In order to obtain such a polyimide, it is necessary to make the polyimide main chain as rigid as possible to exhibit low thermal expansion. When polyimide is synthesized using pyromellitic acid, which has the most rigid structure in existence, it is possible to easily develop low thermal expansion properties, but the polarization of the imide group becomes large and it is not possible to develop low hygroscopicity. Further, in order to lower the dielectric constant, it is possible to introduce fluorine, but this is not preferred because it is expected to increase the structural cost and reduce the reactivity of the acid anhydride.
本発明は、低熱膨張性、低誘電率、低吸湿性(耐水性)
などの優れた特性を有するポリイミドを合成するために
有用な新規酸二無水物を提供することを目的とする。The present invention has low thermal expansion, low dielectric constant, and low moisture absorption (water resistance).
The purpose of the present invention is to provide a novel acid dianhydride useful for synthesizing polyimides having excellent properties such as.

カルボン酸二無水物を発明するに至った。The present inventors conducted various molecular designs for tetracarboxylic dianhydride and evaluated the results. As a result, the heat resistance of the synthesized polyimide decreases with aliphatic, and the main chain is bent, resulting in low thermal expansion. In addition, when polyimide is synthesized using pyromellitic acid, which has the most rigid structure among existing Wi anhydrides, the -R- group, which exhibits low thermal expansion, has heat resistance. If polyimide is synthesized using a polyimide with the expected rigid structure, it will not only be possible to achieve low thermal expansion, but also because the molecular weight of the acid anhydride will increase, the imide, which is the polar part of polyimide, will be synthesized. We thought that the proportion of the ring would be reduced, thereby achieving low dielectric constant and low hygroscopicity, and as a result of intensive study, we found that the structure is suitable for introduction into the -R- group of chemical structural formula [11]. The following structural formula (III) (where n is an integer of 1 to 3) was discovered, and a novel tetracarboxylic dianhydride represented by the above chemical structural formula [1] was invented.
