Abstract: Abstract To investigate the effect of introducing 2,2′-dichloro substituted biphenyl linkage into the polymer backbones on the properties of polyimides (PI), 2,2′-dichloro-4,4′,5,5′-biphenyltetracarboxylic dianhydride (DCBPDA) was polymerized with aromatic diamines, including 2,2′-bis(trifluoromethyl)benzidine (TFMB) in m-cresol to… read more here.

Abstract: A new diamine containing an imidazole structure, 4,4′-(4,5-diphenyl-1H-imidazole-1,2-diyl)dianiline (DIMA), was synthesized to prepare photoconductive polyimides (PIs) with four types of dianhydrides such as 3,3′,4,4′-biphenyltetracarboxylic dianhydride, 4,4′-oxyduphthalic anhydride, 4,4′-(hexafluoroisopropylidene) diphthalic anhydride, and cyclobutane-1,2,3,4,-tetracarboxylic dianhydride, based on… read more here.
