Addition reaction of (3-methyl-3-oxetanyl)methyl acetate (MOMA) with bis(4-mercaptophenyl) sulfide (BMPS) was examined in certain organic solvents. When the reaction of MOMA with BMPS was performed without any catalyst in hexamethylphosphoric triamide (HMPA) and N-methyl-2-pyrrolidone (NMP) at 130Β°C

A new oxetane-containing polyether was synthesized by polycondensation of bisphenol-AF (BPAF) with 3,3-bis(chloromethyl)oxetane (BCMO) using the phasetransfer catalyzed method. The polycondensation proceeded very smoothly in aromatic solvents, catalyzed by quaternary ammonium or phosphonium salts, s
## Abstract This paper describes the synthesis of polymers having spiro orthoester side groups, starting from lactones with methacrylate side groups. The spiro orthoester polymers are synthesized by a reaction with an oxirane. The hydroxyβfunctional lactones 3βhydroxyβ4,4βdimethylβ2βoxotetrahydrofu
Al~traet--The polycondensation of 3,3-bis(chloromethyl)oxacyclobutane with bisphenol-A under phase transfer conditions is reported a possible mesomorphism of these polymers is discussed. Investigations by optical polarization microscopy and DSC are described.
