The relationship between the reduced viscosity and concentation of sulfonated styrene-isoprene- styrene triblock copolymer(SSIS) and its ionomers in toluene and toluene/methanol solutions were studied.
本文报道SIS磺化及离子化后由溶液中分子链形态的不同而导致的溶液的比浓粘度及特性粘数的变化。
The reduced viscosity of TEAA-co-AM and DEB.
研究了共聚物水溶液的流动性质 ,这两类共聚物在水溶液中的比浓粘度都随盐浓度增大而增高 ,这是由于在盐溶液中盐度增大介质极性增强 ,至使大分子中较大烷基逃逸水相并发生自缔合的倾向更强烈的原因。
Effect of Viscosity Ratio on Morphology and Mechanical Properties of PP/HDPE Blend;
粘度比对PP/HDPE共混物材料形态结构与性能的影响
Keeping the composition and processing conditions the same, it is found that the morphology of PP/EOC blend is determined by the viscosity ratio (λ) and the interfacial interaction.
在相同加工条件和共混比例下 ,PP/EOC共混物的形态由粘度比和界面相互作用决定 ,发现粘度比和界面相互作用大时 ,分散相易变形呈纤状分布。
The results showed that the morphologies were not only affected by their interfacial tensions but also affected by the viscosity ratios between the disperse phase and continuous phase.
从聚合物界面张力和熔体粘度比出发对聚合物三元共混体系的形态结构进行了考察 ,结果表明 :三元共混物的形态结构不仅受聚合物界面张力的影响 ,同时聚合物的熔体粘度比对其形态结构也有很大影响 ,分散相粘度较小时 ,共混物易于形成分散型形态结构。
The dependence of specific viscosity on the solution concentration was investigated in presence of poor solvent.
考察了在非良溶剂存在的情况下两种溶液浓度和增比粘度(η8p)的依赖关系,测定了两种溶液中的缠结浓度(Ce)。
