A new aromatic polyamide containing a pendant ethoxycarbonyl group was successfully synthesized from the reaction between 4,4Π-diamino-2Π-ethoxycarbonylbenzanilide and terephthaloyl chloride. The new polymer was soluble in organic solvents such as N-methyl-2-pyrrolidone and dimethylacetamide, and a

Poly(2,5-dimethoxy-1,4-phenylene vinylene) (PDMoPV) prepared via the chlorine precursor route (CPR) exhibits absorption at a shorter wavelength than that obtained by the Wessling method. The polymer fluoresces at a maximum of 505 nm as compared to 540 nm by Wessling method. Both the fabricated ITO-P
## Abstract A series of anion exchange membranes with pyridinium groups were prepared by aminating 100% bromomethylated poly(2,6βdimethylβ1,4βphenylene oxide) with 4βvinylpyridine. These membranes exhibited higher ion exchange capacity, lower water uptake, lower area resistance, and better thermal
