摘　　要：聚电解质在溶液中的性质及形态与所用溶剂有很大的关系,聚合物在不同矿化度的盐水中其分子形态伸展程度不一样,其在溶液中分子尺寸(水动力学半径)也会发生很大改变。通过对抗温抗盐聚合物(KYHPAM-2)和普通HPAM(MO-4000)在不同矿化度的盐水中配成溶液,让其在恒定压力(0.2 MPa)下经过不同孔径滤膜后测定其滤液浓度、粘度、流速等的研究,结果发现聚合物在不同矿化度下水化分子尺寸变化很大,其中MO-4000变化程度远远大于KYHPAM-2,同时进一步证实KY-HPAM-2具有优于MO-4000的抗温抗盐性能。The structural character and the aqueous dimension of electrolytical polymer is associated with salt concentration and species.The extend degree of electrolytical polymer is different in different salt water.Two kinds of electrolytical polymer(MO-4000 and KYHPAM-2) are dissolved in three types of salt water.Solutions are percolated through varied dimension millpore in constant pressure(0.2MPa).The results showed that the aqueous dimension of electrolytical polymer is changed in different salt water and MO-4000's diversification degree is much bigger than KYHPAM-2's.It is suggetion that KYHPAM-2 is better than MO-4000 in resistive temperature and salt.
