Abstract:Diethyl magnesium as a diethyl etherate-dioxanate complex polymerises propylene oxide in a diethyl ether solution to very high molecular weight crystalline polymer. Magnesium dibromide diethyl etherate polymerises propylene oxide in diethyl ether to low polymer. Ethyl magnesium bromide diethyl etherate polymerises propylene oxide in diethyl ether in four distinct kinetic stages. In the first two kinetic stages, polymer similar to that produced by diethyl magnesium is obtained in very low yield. Polymer of RV w… 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.
