摘要
具体地介绍了无规离聚体/极性溶剂体系的溶液行为的显著特征:在低浓度下呈现典型的聚电解质效应,即比浓粘度ηred.(ηsp/C)随着溶液浓度C的降低而急剧地上升的溶液行为。对离子含量、分子量、平衡离子、中和度、小分子盐及溶剂极性诸因素对这一溶液行为的影响以及产生这些影响的本质原因进行了系统的综述,反映了该领域的研究概况。
The marked characteristics of the solution behavior of random ionomer in polar solvent-typical polyelectrolyte behavior,i.e.the reduced viscoity ηred.(ηsp/C) of the solution systems increases remarkably with decreasing polymer concentration,is clearly given in this paper.The effects of ion content,molecular weight, the type of fixed ions and counterions,the degree of neutralization,the presence of simple salts and the polarity of solvents on the solution behavior of random ionomer/polar solvent systems and the essential cause for them are systematically reviewed.A brief account of the research in this field is introduced.
