MATRIX POLYMERIZATION AND POLYELECTROLYTE COMPLEX-FORMATION

We developed a model of the formation of symplexes by photoinitiated matrix polymerization. Symplexes are insoluble in water and all known solvents. They result from contrarily charged polyelectrolytes. In our model a polyelectrolyte is matrix and binder simultaneously. At the matrix a contrarily charged monomer is polymerized radically to the second polyelectrolyte. Different mechanisms are discussed for the matrix polymerization. As polymerizable monomers acrylic compounds with terminal tertiary amino group were used. Modified styrene/maleic acid copolymers served as polyanion. The influence of the composition of the components in this layers on the polymerization rate was investigated. The sensitivity of the developed photo‐material is compared with other photo‐polymerization systems and the conventional photographic materials basing on silver halogenides. A high resolution and an easy fixation result. Copyright © 1990 Hüthig & Wepf Verlag
