聚电解质：溶液性能和在造纸中的应用
为了确定导致较佳聚合物溶液的参数及其在造纸过程中的较佳用途，特别是基于聚丙烯酰胺的不同PEL颗粒用不同的技术方法溶解(超声处理，使用DISPERMAT分散机和Ultra-Turrax等)。 随后，溶解状态尤其通过流变学表征。储存(G')和损失(G“)模量的确定允许在聚合物链的缠结方面陈述聚合物溶液的内部结构。 基于每种溶液状态的流动电位，通过PEL滴定测定溶液中PEL的电荷密度。
Polyelectrolytes: solution behavior and application in papermaking
To determine the parameters which lead to optimal polymer solutions and their optimum use in the papermaking process different PEL granulates particularly based on polyacrylamide were dissolved with different technical methods (ultrasonic treatment, using a DISPERMAT dissolver and Ultra-Turrax? etc.).Subsequently, the states of dissolving were characterized especially by rheology. The determination of storage (G′) and loss (G′′) modulus allows statements to the inner structure of the polymer solutions in terms of entanglements of polymer chains. Charge densities of the PEL in solution were determined by PEL titration based on streaming potential in each solution state.
