ABSTRACT:In the present study, the effects of chargetransfer complex formation and intramolecular fragmentation (side-chain lactonization) in radical copolymerization of tert-butyl vinyl ether (t-BVE) with anhydrides of maleic (MA) and citraconic (CA) acids and the structure-thermal behavior relationships of the resulting copolymers were examined using the 1 H-NMR, FTIR, DSC, and TGA analysis methods. It was shown that copolymerization under the chosen conditions proceeded through intramolecular fragmentation with the formation of ␥-lactone units. Side-chain fragmentation of t-BVE-MA and t-BVE-CA copolymers also was confirmed by TGA and DSC analysis.
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.
