POLYVINYL OCTAL AND IODINE COMPLEX-FORMATION IN LANGMUIR-BLODGETT-FILMS

Monolayers and multilayers of amphiphilic polymers - polyvinyl octals (PVO) with different degree of substitution of hydroxylic groups and t heir compounds with iodine - were investigated. Analysis of the nature of the PVO-iodine interaction suggests some conclusions about the com plex formation between the polymer in monolayers and the halogen disso lved in a subphase. It was found that iodine induces polymeric chain w idening, changes the order in molecular lattice of condensed phase and gives strong elasticity to the monolayer films. The monolayer iodine- PVO complex with different degree of polymer substitution of hydroxyli c groups was stable on water and could be deposited onto hydrophylic s ubstrates.
