Physico-chemical and structural characteristics have been studied of ionic clathrate hydrates of cross-linked (n = 1%) tetraisoamylammonium (TiAA) polyacrylates with different extent of substitution of proton-ions of the carboxylic groups for TiAA cations (x = 77%, 60%, 40%) in the polyacrylate. Powder X-ray diffraction studies have been carried out. All hydrates are isostructural to the earlier studied clathrate hydrate of cross-linked TiAA polyacrylate with x = 100%. The hexagonal structure with the space group P6/mmm and slightly different unit cell parameters (a ~ 12.24 Å, c ~ 12.70 Å) is related to the idealized Hexagonal Structure I of clathrate hydrates. Compositions, phase transition temperatures and decomposition enthalpies of the hydrates have been determined using differential thermal analysis and differential scanning calorimetry. The stability of the hydrates structure decreases with lessening of the content of TiAA cations in the polymeric molecule. The hydrates decomposition temperatures go down from + 14.6 to + 9.8 °C (for x = 100–40%) and the decomposition enthalpies—from 189.1 kJ/mol of hydrate to 84.0 kJ/mol of hydrate (for the same interval of x). The comparison has been made of physico-chemical characteristics of the ionic clathrate hydrates of cross-linked TiAA polyacrylates with those of the hydrates of tetrabutylammonium (TBA) polyacrylates and also of the ionic clathrate hydrates of TBA salts with monomeric anions.

已经研究了交联 ( n  = 1%) 四异戊铵 (TiAA) 聚丙烯酸酯的离子笼形水合物的物理化学和结构特征，其中羧基的质子离子取代了不同程度的 TiAA 阳离子 ( x  = 77%, 60%, 40%) 在聚丙烯酸酯中。已经进行了粉末X射线衍射研究。所有水合物均与早先研究的交联 TiAA 聚丙烯酸酯的笼形水合物同构，x  = 100%。空间群为P 6 /mmm的六边形结构，晶胞参数略有不同 ( a  ~ 12.24 Å, c ~ 12.70 Å) 与笼形水合物的理想六方结构 I 有关。已经使用差热分析和差示扫描量热法测定了水合物的组成、相变温度和分解焓。水合物结构的稳定性随着聚合物分子中TiAA阳离子含量的减少而降低。水合物分解温度从 + 14.6 降至 + 9.8 °C（x  = 100–40%），分解焓从 189.1 kJ/mol 水合物降至 84.0 kJ/mol 水合物（对于相同的x区间））。已经对交联的 TiAA 聚丙烯酸酯的离子笼形水合物与四丁基铵 (TBA) 聚丙烯酸酯的水合物以及具有单体阴离子的 TBA 盐的离子笼形水合物的物理化学特性进行了比较。
