| 摘 要： | 本文合成了一系列不同交联度的聚丙烯酸凝胶，测定了这些凝胶在不同ｐＨ值及温度下的综合溶胀行为，包括用经典的间断称重方法测定溶胀动力学曲线，用溶胀性能自动测定仪测定溶胀应力变化的动力学曲线及平衡溶胀度等。这这类环境敏感材料的应用提供了科学数据。

| Abstract: | Serials of polyacrylic gels with different amount of crosslinker were synthesized.The comprehensive swelling behaviors of the gels were investigated under different PH and temperature f They included the determinationof swelling kinetic curves by both methods of classical weighing and advance swelling stress with the aide of an instrument for automatic determination of swelling property of polymer as well as equilibrium swelling degree. The scientific data were provided for the applications of these materials. |
