Abstract

A methodological approach has been proposed for studying the effect of solvent nature on the adhesive properties of films of binary copolymers with different chain microstructures. The approach is based on a complex analysis of the thermodynamic work of adhesion in polymer–liquid model systems and the results of mechanical tests in combination with quantum-chemical calculations. The approach has been used for the first time for copolymers of styrene and n-butyl acrylate having gradient and random distributions of comonomer units over the chains, with the copolymers being synthesized by radical polymerization with reversible chain transfer. The results obtained have shown that the adhesive properties of the binary copolymer films may be regulated by varying the chemical nature of solvents from which they are formed.

溶剂性质对固体基质上流延形成的二元苯乙烯-丙烯酸正丁酯共聚物薄膜粘合性能的影响

摘要

已经提出了一种方法学方法来研究溶剂性质对具有不同链微结构的二元共聚物薄膜的粘合性能的影响。该方法基于对聚合物-液体模型系统中粘合的热力学功的复杂分析，以及结合量子化学计算的机械测试结果。该方法首次用于苯乙烯和正丁烯的共聚物在链上具有梯度和共聚单体单元的无规分布的丙烯酸丁酯，共聚物是通过自由基聚合和可逆的链转移合成的。所得结果表明，可以通过改变形成二元共聚物膜的溶剂的化学性质来调节二元共聚物膜的粘合性能。
