The Use of Polarized Luminescence for the Examination of the Mobility and Conformational Changes in Polymer Macromolecules in Solution,

Abstract

The authors have investigated the application of polarized luminescence (PL) methods to the examination of mobility and conformational changes of polymer molecules (polymethacrylic acid - PMAC, polyacrylic acid - PAC and polymethylmethacrylate - PMMA and others) in solution. For the study of the mechanism of mobility appearing in polarized luminescence, PMMA macromolecules were used. Non-luminescent macromolecules (PMAC, PAC and PMMA) can be examined by the PL method, provided that luminescent groupings can be attached to them by covalent bonds. Samples of PMMA were synthesized containing covalently joined luminescent 9-anthrylacyloxymethane groups (one group on 170 and on 1000 links of polymer, which with a mol. wt. of PMMA 300,000 amount to 18 and 3 groups respectively on one macromolecule).
