Anew kind of monomersincluding aromaticspirodilactone———5
5′-carboxy-7
7′-dioxo-2
2′-spirobi(benzo-[c]tetrahydrofuran) is synthesized from m-xylene and paraformaldehyde. It is converted to a series of polyamides and polyesters by means of low temperature solution polycondensation and interfacial polycondensation . NMR and I Rspectra
solubility
mechanicaland thermal properties of allthese polymers areinvestigated . The polymers have high glass transition temperatures and good thermal oxidative properties. All polyamides have high viscosity and good solubility in strong polar organic solvent
flexible and tough films possessing good tensile properties.
