Notizen:
Condensation polymers were obtained by the reaction of several aromatic dihydroxy compounds (especially substituted hydroquinones) and 1,3-dimethyl-2,4-dithio-2,4-dichloro-1, 3-diaza-2,4-diphosphetidine. The condensation polymers thus obtained were investigated on their thermal behavior. The thermal stability is lowered in the following series: hydroquinone ≈ resorcinol 〉 tetramethylhydroquinone ≫ tetrachloro-hydroquinone ≈ tetrafluorohydroquinone ≫ pyrocatechol. The infrared spectra of these new polymers have been measured and are discussed in detail.
