Abstract

Abstract 2-Furyloxirane (FO), a monomer usually obtained from a nonpetroleum route, was prepared from the epoxidation reaction of furfural and trimethylsulfonium chloride. About 200– 300 g FO can be obtained in each preparation process. Although anionic polymerization of FO generally gives low-molecular-weight polymers even after long periods of polymerization, the reaction was greatly improved when macrocyclic ether was used as a ...
