3,4-Dihydrocoumarin (DHC), a six-membered phenolic lactone derived from natural resources, which does not undergo homopolymerization, was subject to ring-opening anionic copolymerization with several epoxides (ethylene oxide, propylene oxide, 1,2-butylene oxide, styrene oxide, and 2-ethylhexyl glyci...
