Abstract:ABSTRACT:The structure of a range of systematically synthesized polyamides, as well as some corresponding component molecular fragments, were studied using wide angle X-ray scattering and computer modeling methods. The molecules all contained tetrasubstituted biphenyls within the amide components, while the aliphatic acid components contained different lengths of the alkyl sequence. A model representing the molecular packing in fiber samples is proposed. It indicates that the polymer backbones are organized in… Show more
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.
