Abstract
AbstractThe derivatives of poly‐3,3‐bis(chloromethyl)oxacyclobutane were prepared by the reaction of the chloromethyl group with organic alkali salts at 100–130°C. in dimethyl sulfoxide. Various reagents were used, including sodium cyanide, sodium acetate, sodium thiophenolate, sodium phenolate, sodium methoxide, sodium diethyl malonate, and potassium phthalimide. For all the substitution reactions, the infrared spectra and elementary analyses substantiated the structures of the designated products. The intrinsic viscosities of the derivatives decreased with increasing the reaction time. It was found that the ions of these salts are strong nucleophiles in dimethyl sulfoxide.
