Abstract

Semicrystalline polyimide, Regulus™ NEW-TPI, is a thermoplastic polyimide produced by mitsui Toatsu. This aromatic polyimide possesses outstanding heat resistance, high tensile strength, excellent electrical properties, and strong solvent resistance. It has become the subject of recent study in our group [1–6] and others [7–13]. The flexible ether and meta linkages in the monomer unit lower its glass transition temperature (Tg) to 250°C in quenched amorphous material.
