preparation example Construction

[0075]

[0076] The polyamic-acid composition inject|throws in the said preparation ratio the polyamic acid of the said (A) component, and the acrylic compound of (B) component, and mixes it and prepares it. When preparing a polyamic acid composition, it is preferable to use a solvent as needed.

[0077] [Polyimide composition]

[0078] The polyimide composition of this embodiment heat-processes a polyamic-acid composition, and is obtained by imidating the polyamic acid of (A) component. The imidization method is not particularly limited, for example, heat treatment is suitably used, that is, heating is performed at a temperature in the range of 80° C. to 400° C. within a time range of 1 minute to 60 minutes.

[0079] In the polyimide composition of this embodiment, it is considered that the acrylic compound exists in the polyimide in a non-bonding state. Here, the "non-bonded state" means that the functional group of the acrylic compound does not form a bond with the poly...

no. 1 Embodiment approach

[0094] The first embodiment of the polyimide having the function of trapping sulfur-containing organic compounds can use the following polyimide composition obtained by heat-treating the following polyamic acid composition to imidize it. Obtain, the polyamic acid composition comprises following component (A) and component (B):

[0095] (A) polyamic acid having a weight average molecular weight in the range of 10,000 to 150,000, and

[0096] (B) an acrylic compound, and

[0097] The said (B) component is contained in the range of 0.1 weight part - 60 weight part with respect to 100 weight part of said (A) components. In 1st Embodiment, the said compound can be used for the polyamic acid of (A) component, and the acrylic compound of (B) component.

no. 2 Embodiment approach

[0099] The thermoplastic polyimide of the second embodiment is a thermoplastic polyimide obtained by heat-treating polyamic acid obtained by the reaction of an aromatic diamine and an aromatic tetracarboxylic dianhydride to imidize it. amine. Here, the aromatic diamine contains an aromatic diamine having a radically polymerizable unsaturated bond within a range of 2 to 6 carbon atoms, and the amount of the radically polymerizable unsaturated bond per 1 g of the polyamic acid is 0.096 In the range of mmol~3mmol.

[0100] The metal-clad laminate and the circuit board produced using the thermoplastic polyimide of the second embodiment can maintain the gap between the metal layer and the resin layer even after 1000 hours or more are immersed in oil at 150°C containing a sulfur compound. of high adhesion. As described above, in the second embodiment, the radically polymerizable unsaturated bond in the thermoplastic polyimide functions as a trapping means for trapping sulfur compo...

Abstract

The present invention provides a polyamide acid combination, a polyimide combination, a laminated body, a circuit board, a usage thereof, the manufacturing method of the laminated body and the manufacturing method of the circuit board. The present invention provides the laminated body and the circuit board, the adhesive force between the metal layer and the resin base material of which can not decrease even on the condition of repeatedly exposing in high temperature and in oil element. The polyamide acid combination includes: an element (A) named polyamide acid combination and its weight average molecular weight between 10000 to 150000, and an element (B) named acrylic compound, and every range from 0.1 to 60 parts by weight containing the element (B) relative to the 100 parts by weight of the element (A). Each 1g of the element (A)containing the amount of free radical polymerized unsaturated bond is below 3mmol, the value of the element (B) [the number of (methyl) propylene acyl of one molecule/molecular weight] is above 0.001.

Description

technical field [0001] The present invention relates to a polyamic acid composition, a polyimide composition, a laminate, a circuit board, a method for using the same, a method for manufacturing the laminate, and a circuit board, which can be used for manufacturing flexible printed wiring boards, etc. manufacturing method. Background technique [0002] In recent years, with the advancement of miniaturization, weight reduction, and space saving of electronic equipment, flexible printed wiring boards (Flexible Printed Wiring Boards) (Flexible Printed Wiring Boards) that are thin, lightweight, flexible, and have excellent durability even after repeated bending Printed Circuits, FPC) demand increased. FPC can also be installed in a three-dimensional and high-density manner in a limited space. Its use is expanding in parts such as wiring, cables, and connectors. [0003] In automobiles, from the viewpoint of weight reduction, various parts such as the surroundings of the engin...
