preparation example Construction

[0016] The invention provides a kind of preparation method of soluble polyamic acid ester resin, the method comprises the following steps:

[0017] 1) reacting fluorine-containing aromatic diacid diester with thionyl chloride to form corresponding fluorine-containing aromatic diacid diester;

[0018] 2) dissolving the aromatic diamine and its mixture in an organic solvent to form a homogeneous solution;

[0019] 3) Adding the aromatic diamine and its mixture solution in batches to the fluorine-containing aromatic dichloride diester solution;

[0020] 4) Then add the molecular weight regulator, and the reaction mixture generates polyamic acid ester resin solution by polycondensation reaction at room temperature;

[0021] 5) Pour the resin solution into excess water to precipitate solid resin;

[0022] 6) Wash and dry the solid resin for use.

[0023] The positive photosensitive polyamic acid ester resin composition of the present invention is characterized in that the fluori...

Abstract

The invention provides a positive photosensitivity polyamide acid ester resin composition, a preparation method and application thereof. The resin composition comprises the following components in portion by weight: 10 to 70 portions of the soluble polyamide acid ester resin, 100 to 1,000 portions of an organic solvent, 0.1 to 50 portions of a photosencitizer, 0.1 to 50 portions of a photosensitizer additive, and 0.1 to 50 portions of a built-in adhesion promoter, wherein the soluble polyamide acid ester resin is prepared from aromatic diacid chloride diester containing fluorin, aromatic diamine and mixture thereof, and a molecular weight conditioning agent. The positive photosensitivity polyamide acid ester resin performs a photodegradation reaction after exposure through ultraviolet ray (i ray and g ray), and after an exposure area is dissolved by an aqueous solvent, a pattern with high resolution can be obtained. Furthermore, a polyimide layer membrane formed after being heated and cured has low specific inductive capacity, low water absorbing capacity, excellent thermal stability, mechanical performance and optical performance.

Description
