二层法双面挠性覆铜板用热塑性聚酰亚胺的合成与应用研究

选用合适的单体芳香二酐二苯甲酮四酸二酐（BTDA）、2,2’-双4-（3,4-二羧基苯氧基）苯基]丙烷四羧酸二酐（BPADA）和芳香二胺3,3′，5，5′-四甲基-4,4′-二氨基二苯甲烷（AMD）、4,4′-二氨基二苯甲烷（MDA）、4,4′-二氨基二苯醚（ODA），3,4＇-二氨基二苯醚（3，4＇-ODA）根据不同配比反应得到聚酰胺酸，用乙酸酐／三乙胺经化学亚胺化得到热塑性聚酰亚胺（TPI），将其用N-甲基吡咯烷酮（NMP）溶解配成一定固含量的胶液，涂覆铜箔烘干溶剂得到二层挠性覆铜板（2L—FCCL），然后将2L—FCCL高温压合制备双面挠性覆铜板，其剥离强度较高。

Synthesis and Applied Research on Polyimide Used for 2-Layer Double-side Flexible Copper Clad Laminate

Suitable monomer aromatic dianhydride(BTDA and BPADA) and aromatic diamine(AMD,MDA,ODA and 3,4'-ODA) were selected to get thermoplastic polyimide(TPI) via chemical imidization with acetic anhydride/triethylamine.Then made it dissolve in NMP to prepare glue solution with certain solid content.And 2-layer flexible copper clad laminate(2L-FCCL) was made with casting technique.2L-FCCL was laminated to make double-side flexible copper clad laminate with lamination technique.It has high peel strength.
