A series of copolymers from 3,3 ,4,4 -benzophenonetetracarboxylic dianhydride and 3,3 ,4,4 -biphenyltetracarboxylic dianhydride and two diamines, 4,4 -diaminodiphenylether and 3,5-diaminobenzoic acid, were synthesized. The influence of various ratios of diamines on the properties of polymers were investigated. A preliminary study on the potential of using the carboxylic acid group for substitution was carried out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
