Abstract

Poly(ethylene glycol) (PEG) and poly (ethylene-co-acrylic acid) (EAA) form coordination complexes with iron(III) chloride ($FeCl_3$). The structures of these complexes have been studied by using Fourier transform infrared (FTIR) spectroscopy. The crystalline morphological structure of PEG-$FeCl_3$ complexes depends on the weight ratio of PEG/$FeCl_3$. Both PEG-$FeCl_3$ and EAA-$FeCl_3$ complexes are very susceptible to UV photodegradation. Polarized optical microscopy has been applied to study the crystalline morphological changes in the PEG-$FeCl_3$ complexes before and after UV irradiation. Photodegraded products of both PEG-$FeCl_3$ and EAA-$FeCl_3$ complexes have been identified by using FTIR spectroscopy. The presence of the $FeCl_3$ in these complexes markedly accelerates their photodecomposition.
