Efficient synthesis of 2-methylene-4-phenyl-1,3-dioxolane, a cyclic ketene acetal for controlling the NMP of methyl methacrylate and conferring tunable degradability

Abstract

The efficient and reliable synthesis of 2-methylene-4-phenyl-1,3-dioxolane (MPDL) was reported and MPDL was used as a controlling comonomer for nitroxide-mediated polymerization of methyl methacrylate to give degradable copolymers.
