trans Development of high performance heat resistant transparent polyimides based on trans-,,, -cyclopentanetetracarboxylic dianhydride Takaaki Uno Takashi Okada Igor Rozhanskii Toshimitsu Kikuchi Kohei Goto Recently, much attention has been paid to transparent engineering plastic for optical applications, such as touch panel substrates, flexible circuits, flexible display substrates, LED and lens materials. Polyimides prepared from alicyclic diamines and or dianhydrides generally have good transparency in the visible region. In general, there is a trade-off between heat resistance and solubility of such polymers. The most of semi-aromatic polyimides show excellent solubility and transparency, but they lack some of the useful features of fully aromatic polymers. In this paper, we report the properties of semi-aromatic polyimides synthesized from trans-,,, -cyclopentanetetracarboxylic dianhydride t-cpda. These polyimides show high heat resistance Tg, combined with good solubility, low thermal expansion ppm and low water absorption. Polyimides derived from t-cpda are considered to be suitable materials for flexible transparent substrates. JSR TECHNICAL REVIEW No.122/2015 13
