The simplified theory of mixed polymer dilute solution vras used to identify that some interactions were existed between NaCS and PVA. But the polyelectrolete property of NaCS was not affected by the interactions.

• 结果表明,PVA组分的存在并不影响NaCS的聚电解质性质,两组分间也没有强烈的相互作用,但NaCS与PVA之间仍有一定的弱相互作用,使NaCS的特性粘度在极微量的PVA存在下大幅度提高,并产生极大值。
