Definitions
- the present invention relates to polyamic acid. More specifically, surface protective films and interlayer insulating films for semiconductor elements, insulating layers and spacer layers for organic electroluminescence elements (organic EL elements), planarization films for thin film transistor substrates, insulating layers for organic transistors, flexible printed boards, and flexible displays It is related with the polyamic acid used suitably for the board
- Polyimide is used in various fields including semiconductor applications due to its excellent electrical insulation, heat resistance and mechanical properties.
- polyimide is often insoluble in a solvent and heat infusible, so that direct molding is difficult.
- varnish a solution containing a polyamic acid that is a precursor of polyimide
- the polyamic acid polymerization solution can be used as it is, or the polyamic acid can be dissolved in a solvent.
- the degree of polymerization of the polyimide is controlled by adjusting the molar ratio between the acid anhydride group of the acid dianhydride of the monomer and the amino group of the polyvalent amine compound or diamine compound. The viscosity of can be adjusted appropriately.
- the degree of polymerization of the polyimide obtained using this varnish is equal to the degree of polymerization of the original polyamic acid, and high mechanical properties cannot be obtained.
- Patent Documents 1 and 2 water and alcohol are added at the time of polyamic acid polymerization to seal the acid anhydride ends and control the degree of polymerization (Patent Documents 1 and 2), or amino acid ends are blocked to polymerize the polyamic acid.
- a method for controlling the degree (Patent Document 3) has been reported. According to these methods, when the end-capping agent is eliminated at the time of firing, the acid anhydride group or amino group is regenerated and can participate in the polymerization again. As a result, the degree of polymerization of polyimide is improved, and a polyimide film having excellent mechanical properties can be obtained.
- Non-Patent Documents 1 to 4 a method of introducing a thermopolymerizable group into a polyamic acid terminal using a terminal blocking agent containing a thermopolymerizable group has been reported (Non-Patent Documents 1 to 4).

Therefore, in order to obtain a polyimide having a sufficiently high degree of polymerization by these methods, it is necessary to adjust the ratio of the sealed terminal amino group and terminal acid anhydride group to be equal.
- Non-Patent Documents 1 to 4 either a terminal acid anhydride group or a terminal amino group is sealed with a terminal sealing agent containing a thermally polymerizable group.
- the end-capping agent is not eliminated and the thermally polymerizable groups react with each other. Therefore, even if there are polyamic acids having an acid anhydride group or amino group at the end, they remain unreacted at the time of firing, so a sufficient degree of polymerization cannot be obtained, and the polyimide film obtained by firing is high. Mechanical properties cannot be obtained.

That is, it is possible to reduce the viscosity of the varnish and to provide a polyamic acid in which the polyimide film has excellent mechanical properties after firing.
