Abstract
Aqueous solutions of linear poly(2-ethyl-5,6-dihydrooxazine) and eight-armed star-shaped poly(2-isopropyl-2-oxazoline) have been studied by light scattering and turbidimetry. The influence of the duration of annealing at temperatures above the phase separation temperature on the behavior of the solutions has been analyzed. It has been shown that the characteristics of linear polymer solutions do not vary in the studied annealing time interval. The cloud point of star polymer solutions also does not depend on the annealing time. However, significant changes have been observed at the microscopic level, namely, irreversible aggregation due to the interaction of hydrophobic segments of poly(2-isopropyl-2-oxazoline) arms formed during annealing at a high temperature.
期刊介绍：
Polymer Science, Series C (Selected Topics) is a journal published in collaboration with the Russian Academy of Sciences. Series C (Selected Topics) includes experimental and theoretical papers and reviews on the selected actual topics of macromolecular science chosen by the editorial board (1 issue a year). Submission is possible by invitation only. All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
