Abstracts

EN

Commercially available poly-(1,4-phenylene sulfide) = PPS with trade names TEDUR and RYTON contain a great amount of Fe(III) (order of 10^{20} Fe/gram) as shown by electron spin resonance spectra. The curing of the pure and Fe-doped (0.2% Fe_2O_3) PPS polymers proves that Fe(III) can be used for improvement of the PPS strength by increasing the polymer cross-linking and a decrease in the polymer crystallinity degree as shown by X-ray diffraction.
