摘要
通过对聚乙烯醇17-99H、100-37H、100-50H及100-60L的特性粘度(浓度与比浓粘度)进行研究,发现比浓粘度与浓度不成直线关系,出现了"W"折线图,即得不到聚乙烯醇的特性粘度。图中的"峰""谷"与聚乙烯醇的组成关系,有待下一步分离、纯化后实验研究求证。
The intrinsic viscosity of poly(vinyl alcohol) 17-99H, 100-37H, 100-50H and 100-60L was studied respectively, which could not obtain the intrinsic viscosity. An observation from the study result was "W" graph, which described the relationship between concen tration and viscosity. This study indicated that the consist of poly(vinyl alcohol) need to be done later.
