摘要

合成了一些脂环（co）聚酰亚胺，研究了聚合物片段与溶剂分子之间形成的电荷转移配合物（ctc）对（co）聚合物性能的影响。结果表明，含金刚烷单体的存在显著降低了聚酰亚胺的分子间相互作用，从而对聚酰亚胺的透光率、色度等光学性能产生了积极影响。使用1,2-二氯苯作为溶剂代替亚砜可以得到更透明的聚酰亚胺。根据量子化学计算，这是由于ctc效应的减弱。

Effect of the inter-chain interaction and the nature of solvent on the optical properties of alicyclic (co)polyimides: an experimental and theoretical study

A number of alicyclic (co)polyimides were synthesized and the effect of charge transfer complexes (CTCs) formed between the polymer fragments and solvent molecules on the properties of the (co)polymers was studied. It was shown that the presence of an adamantane-containing comonomer significantly reduces intermolecular interactions, which has a positive effect on the optical properties of the polyimides including light transmittance, chromaticity, etc. The use of 1,2-dichlorobenzene as solvent instead of sulfolane leads to more transparent polyimides. According to quantum chemical calculations, this is due to a decrease in the effect of CTCs.
