The volumetric (partial and apparent molar volumes) and calorimetric properties (apparent heat capacities) of aqueous cationic polyelectrolyte solutions - ionenes - were studied using the oscillating tube densitometer and differential scanning calorimeter. The polyion's charge density and the counterion properties were considered as variables. The special attention was put to evaluate the contribution of electrostatic and hydrophobic effects to the properties studied. The contribution of the CH group of the polyion's backbone to molar volumes and heat capacities was estimated. Synergistic effect between polyion and counterions was found.
使用振荡管密度计和差示扫描量热仪研究了阳离子聚电解质水溶液（紫罗碱）的体积性质（偏摩尔体积和表观摩尔体积）和量热性质（表观热容）。将聚离子的电荷密度和抗衡离子性质视为变量。特别关注评估静电和疏水作用对所研究性质的贡献。估算了聚离子主链中-CH基团对摩尔体积和热容的贡献。发现了聚离子与抗衡离子之间的协同效应。
