Preparation and properties of a novel quaternary copolymerized thermoplastic polyimide
A series of quaternary copolymerized thermoplastic polyimides (PI) films with good thermal resistance has been synthesized via two-step method from bicomponent isomeric dianhydrides, 2,3′,3,4′-biphenyltetracarboxylic dianhydride (α-BPDA) and 3,3′,4,4′-biphenyltetracarboxylic dianhydride (s-BPDA), an...
