Photophysics, photochemistry, and optical properties of polyimides
Abstract This review discusses charge transfer (CT) interactions in wholly aromatic polyimides (PI). Discussion was extended to the influence of CT interactions on PI properties, i.e. photophysics,Expand

Poly(ester imide)s Possessing Low Coef-cient of Thermal Expansion and Low Water Absorption
The film properties of polyimides (PIs) containing para-ester linkages in the main chains, poly(ester imide)s (PEsI) are reported in this paper. An ester-containing dianhydride monomer (TAHQ) wasExpand

Spontaneous molecular orientation of polyimides induced by thermal imidization (6). Mechanism of negative in-plane CTE generation in non-stretched polyimide films
Abstract The mechanism of negative coefficient of thermal expansion (CTE) generation for non-stretched polyimide (PI) films is proposed in this work. Negative CTE behavior was observed in someExpand
