New oppotunities for metal ions sorptions and nanothechnologies. popup.stage_title Head Kutsevol Natalia Vladimirovna, Доктор хімічних наук Registration Date 13-01-2012 Organization Taras Shevchenko Kiev university popup.description2 Star-like copolymers dextran-polyacrylamide (D-PАА) with various number and lengh of grafted polyacrylamide chains in non-ionic and anionic forms were syntheized. The effect of initial architecture of branched macromolecules on their intramolecular structure amd behavior in solution were studied. It was shown that these copolymers correspond the theoretical model of spherical brushes with different size of dextran core and polyacrylamice corona. It was established that copoilymers D-PAA have more compact structure in wather solution in comparison with linear PAA. It was shown that the distance between grafts determines the conformation of grafted chains. It was established that intramolecular structure of branched polymers effects the degree of their conversion to anionic derivatives of copolymers D-PAA.
