Abstract

Polymer-polymer and salt-polymer interactions of seven electrolytic complexes based on alpha-liydi-omega-oligo(oxyethylene)h hydroxy-poly[oligo(oxyethlene)oxydimethylsililene] and delta-MgCl2 were studied. This aim was pursued by means of an accurate medium and far FT-IR spectroscopic analysis. By using the decomposition and difference spectroscopy techniques, intensity and frequency of terminal OH and CO stretchings were evaluated in order to detect the presence of anion clusters build up by the coordination or Cl- with -OH groups. The number of chlorine anions per chain coordinated magnesium was established. This analysis allowed us to gain a complete structural picture for these materials, pointing out three possible coordinations of magnesium by polyethereal chains.
