In this study, Our attention has been focused on a pair of polymers having attractive interaction such as coulombic and charge transfer interactions. 1,3,5-triazine-containing polymers and nitrated poly(styrene)(NPS) were used as electron-donor polymers and electron-acceptor polymers, respectively. The relationship between dispersion of NPS in these composites and their mechanical properties was investigated. The following results could be obtained in this study.(1) 1,3,5-Triazine-containing polymers(PTX) and (PTH) with high molecular weights could be prepared from 6-dibutylamino-1,3,5-triazine-2,4-dithiol and α, α'-dibromo-p-xylene or 1,6-dibromo-n-hexane by the two phase polycondensation reaction with phase transfer catalyst, respectively.(2) The composites of (PTX) or (PTH) with poly(styrene) having various nitro group content could be obtained by the solution blend in chloroform. (PTX/NPS)composite films were more transparent than (PTH/NPS)composite films because of better miscibility between PTX and NPS. Nitration of poly(styrene) improved miscibility between PTX or PTH and NPS, which enhanced their tensile strength.(3) Mechanical properties of the PTX films were greatly improved by blending with NPS in comparison with those of the PTH films.

在这项研究中，我们的注意力集中在一对具有吸引相互作用的聚合物上，例如库仑相互作用和电荷转移相互作用。含1,3,5-三嗪的聚合物和硝化聚苯乙烯(NPS)分别用作电子给体聚合物和电子受体聚合物。研究了 NPS 在这些复合材料中的分散度与其机械性能之间的关系。本研究得到以下结果：(1)以6-二丁基氨基-1,3,5-三嗪-2,4-二硫醇和α,α'-二溴对二甲苯或1,6-二溴正己烷为原料,通过相转移两相缩聚反应制备高分子量的含1,3,5-三嗪聚合物(PTX)和(PTH)。 (2)(PTX)或(PTH)与不同硝基含量的聚苯乙烯的复合材料可以通过在氯仿中的溶液共混得到。 (PTX/NPS) 复合薄膜比 (PTH/NPS) 复合薄膜更透明，因为 PTX 和 NPS 之间的混溶性更好。聚苯乙烯的硝化改善了PTX或PTH与NPS之间的混溶性，从而提高了其拉伸强度。(3)与PTH薄膜相比，与NPS共混的PTX薄膜的机械性能得到了极大的改善。
