Аннотация:
Various types of structural organization of polycomplex gels based on a lightly crosslinked anionic sulfonate gel and Astramol poly(propyleneimine) dendrimer of the fourth generation were studied. It was shown that along with macroscopic two-phase structure of the core-shell type, which is formed in the process of activated dendrimer sorption by anionic gel, a microheterogeneous composite with polycomplex phase particles of micron dimensions uniformly distributed in the network matrix is also formed. Such microheterogeneous composites are formed as a result of dendrimer molecule redistribution in a lightly crosslinked anionic gel during dendrimer charge change. The parameters of the microheterogeneous structure of polycomplex gel forms were evaluated by the laser scattering technique. It was found that the size of dendrimer aggregates depends on the value of the network degree of swelling. © 2010 Allerton Press, Inc.
