Abstract:Polydimethylsiloxane and poly(ethylene oxide) randomly grafted polyamide (PA-g-SE) and poly(amide-imide) (PAI-g-SE) were prepared by a macromonomer method, and the effect of the backbone structure on the thermal property and the solubility of the graft copolymers was investigated. Glass transition temperature (Tg) of PAI-g-SE was observed in the range of 160 -170°C, whereas Tg of PA-g-SE was not observed in the range of 0 -300°C. The obtained PAI-g-SE was soluble in some solvents such as DMSO, DMF, THF and chl… Show more
scite is a Brooklyn-based startup 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 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.
