BLOCK COPOLYMER OF IMIDE/AMIDE ACID, PROCESS OF PREPARING THE SAME AND PROCESS OF MAKING FLEXIBLE METAL-POLYIMIDE LAMINATE USING THE SAME

摘要

The present invention already provides a method for producing de / polyamide acid block copolymer, and method of manufacturing a flexible polyimide metal-clad laminate using the above block copolymer. ; More particularly, the present invention is (a) consists of a polyamide acid block and connected via the amide bond and imide block is connected through an imide bond; (B) the imide block is formed from a first imide oligomer of the acid repeating units from 1 to 20 The reaction product of the anhydride and the first diamine; (C) The acid amide blocks are shown to bind to the imide oligomer is extended, the second acid is formed from an acid amide reaction product of the anhydride and the second diamine; Provides the imide / polyamide acid block copolymer characterized by; (d) the rotational viscosity of the final copolymer will of 800-2300 poise. ; Shows the operational effects, such as the imide / polyamide acid block copolymer is thermally stable and inert already exerted from the de-block properties and excellent film formability sea component and polyamide employed for the solvent to be exerted from the acid block. ; In addition, the present invention is (i) a first acid anhydride to m + 1 and the first diamine: m or m: m + 1, is reacted in a molar ratio of (where, m is an integer of 1 to 10), the repeating units 1 to 20 a first step of obtaining a de already oligomers; Characterized in that it comprises a; and (ⅱ) a second step of combining the polyamide acid block to the second acid anhydride and the imide block derived by the reaction by the addition of 2-diamine, from the imide oligomer in the imide oligomer which provides a method for producing an imide / polyamide acid block copolymer. ; The manufacturing method compared to the conventional method, significantly reducing the heating time, and to speed up the whole process efficiently control the physical properties of the polymer, while the final creation to greatly reduce the cost of producing a polyimide-based resin It indicates the effect to provide a polyimide-based resin of excellent properties. ; In addition, the present invention for preparing the imide / amino acid block copolymer by incorporating heating by applying on a metal plate a copper foil, etc. or bonding the metal plate and the polyimide film using the imide / amino acid block copolymer flexible metal polyimide laminate It provides a method. ; The manufacturing method illustrates the effect of producing a flexible laminate within the solderability, the peel strength, dimension stability and excellent physical properties at a low production cost. ; Polyimide, polyamide acid, a block copolymer, a flexible metal polyimide laminate
