Popis: | Star-shaped polymers with the calix[8]arene core and poly(2-isopropyl-2-oxazoline) and poly(2-isopropyl-2-oxazoline)–poly[3-(2-oxazoline)propionic acid] block copolymer arms at various ways of attaching blocks to the core are synthesized by ring-opening cationic polymerization. Luminescent labels are introduced by the esterification of carboxyl groups by diazomethane derivatives. In order to obtain interpolymer complexes luminescently labeled poly(methacrylic acid) and poly(acrylic acid) are synthesized. The resulting polymers are characterized by the methods of molecular hydrodynamics and optics. Interpolymer complex formation in the aqueous solutions of the polymers is studied by polarized luminescence. It is shown that the chemical structure of the polyoxazoline fragment and the way of its addition to the core influence the structural and dynamic characteristics of the interpolymer complexes with polycarboxylic acids and their stability. |
