Abstract

It has been shown that there is a significant difference in the stoichiometry of the complexes of fully and partially saponified poly(vinyl alcohol) (PVA) with lithium chloride and bromide. This phenomenon is explained based on the concept of hybrid interpolymer complexes. In the Raman spectra of the complexes, a single band is observed at 1445 cm^–1.

聚乙烯醇与氯化锂、溴化物配合物的化学计量学与皂化度的关系

研究表明，完全皂化聚乙烯醇（PVA）与部分皂化聚乙烯醇（PVA）与氯化锂和溴化物的配合物在化学计量上存在显著差异。基于杂化聚合物间配合物的概念解释了这一现象。在配合物的拉曼光谱中，在1445 cm-1处观察到一个单波段。

期刊介绍： Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). 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. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
