The preparation of some novel dicarboxylic acids* containing one or more phenoxyacetic acid group(s) is described. The acids give polyamides of high molecular weight when condensed with diamines. Some properties of the polyamides with hexamethylenediamine and decamethylenediamine are described.
The preparation of some novel dicarboxylic acids containing two p‐phenylene groups is described. The acids give polyamides of high molecular weight when condensed with diamines. Some properties of the polyamides with hexamethylenediamine and decamethylenediamine are described.
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.
