Effects of polyamide elastomer on the morphology, crosslink density, mechanical, and oil‐resistant properties of acrylonitrile‐butadiene rubber/polyamide elastomer vulcanizates
Abstract:Polyamide elastomer (PAE) is a novel material which may improve the performances of acrylonitrile‐butadiene rubber (NBR). This work uses equilibrium swelling and rheological apparatus to study the effects of the PAE content on the overall crosslink densities of NBR/PAE vulcanizate. The presence of PAE significantly increased the overall crosslink density. During the aging stage, the overall crosslink density first increased and then decreased with increasing aging temperature from 25 to 150°C. There was a line… 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.
