Abstract:Oxazoline-functionalized polypropylenes were synthesized by using the rac-Et[1-Ind] 2 ZrCl 2 /MAO catalyst system. The used comonomers were 2-(9-decene-1-yl)-1,3-oxazoline (R-Ox1), 2-(9-decene-1-yl)-4,4-dimethyl-1,3-oxazoline (R-Ox2), and 2-(4-(10-undecene-1-oxy)phenyl)-1,3-oxazoline (R-Ox3). The oxazolines reduce the catalyst activity in the order R-Ox3 Ͼ R-Ox1 Ͼ R-Ox2. By the addition of triisobutylaluminum (TIBA), the catalyst poisoning is reduced and is most pronounced in the R-Ox1-and R-Ox2-containing sys… 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.
