Solvent effects on polymers
WebThe combination of polymers and surfactants can offer myriad effects, such as controlling interfacial properties, network formation, and rich phase behavior. The latter effect is particularly relevant in the context of the solubilization of water-insoluble polymers [4]. Lignin is an example of a polymer that is insoluble in water and many other WebThe surprising result was the generalization that η o for poor-solvent systems increases with concentration faster than for good-solvent systems, so that eventually η o becomes far …

Did you know?
WebThe surprising result was the generalization that η o for poor-solvent systems increases with concentration faster than for good-solvent systems, so that eventually η o becomes far greater with poor solvents. This behavior is enhanced with polar polymers, and is not explainable on the basis of entanglements in the usual sense. WebAug 2, 2001 · Solvent properties such as polarity, volatility and specific interaction properties with the polymer material are important factors in the process of surface …
