Abstract

The influence of polymer-solvent noncovalent interactions on conformational order in macromolecules as a reason behind the structural plasticization of polymers is considered. The films of styrene-n-butyl acrylate copolymers of various microstructure and composition formed from solutions in solvents of different nature (toluene, acetone) are studied by ATR IR spectroscopy and quantum-chemical simulations. It is shown that the conformational structure of a macromolecule changes through formation of “nucleus” ordered structures. According to the metrological treatment of the measurement data, the absorption bands of the functional groups of the copolymers whose ratio of optical densities may be used as a structural parameter adequately describing “nucleus” conformational changes in the elementary unit are chosen.

聚合物溶剂非共价键在共聚物基本单元构象顺序形成中的作用

摘要

考虑到聚合物-溶剂非共价相互作用对大分子构象顺序的影响，这是聚合物结构增塑背后的原因。苯乙烯的膜ñ通过ATR红外光谱和量子化学模拟研究了由不同性质的溶剂（甲苯，丙酮）中的溶液形成的各种微观结构和组成的丙烯酸丁酯共聚物。结果表明，大分子的构象结构通过“核”有序结构的形成而改变。根据测量数据的计量处理，选择共聚物的官能团的吸收带，这些吸收剂的光密度比可以用作足以描述基本单元中“核”构象变化的结构参数。
