摘要

Poly(acrylic acid) and N-phenylbenzothioamide have been synthesized under laboratory conditions. The purityof products has been checked by FTIR and NMR spectroscopy. The obtained N-phenylbenzothioamide has been used formodification of poly(acrylic acid) properties. The prepared blend of PAA contained small amout of dopant (1-5 wt %).Thermal and photochemical stability of obtained specimens were investigated using UV-Vis spectroscopy andthermogravimetric analysis. Crosslinking yield was estimated by extraction of insoluble gel formed. It was found that N-phenylbenzothioamidestabilizes poly(acrylic acid) during UV-irradiation which is explained by efficient crosslinkingreaction.
