NaCS/PVA混合稀溶液的性质

SODIUM CELLULOSE SULFATE HALF-ESTER/POLYVINYL ALCOHOL DILUTE SOLUTION PROPERTIES

采用乌氏粘度计研究了纤维素硫酸半酯钠盐(NaCS)与聚乙烯醇(PVA)混合稀溶液的性质。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。

The dilute solution of Sodium-Salt of celluloes sulfate half-ester (NaCS) blended with polyvinyl alcohol (PVA) was studied by Ubbelohde viscometry at various conditions. 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.
