(ProQuest: ... denotes formulae/symbols omitted.)Investigation of the concentration dependence of the size and type ... aggregation in aqueous solutions at 25 degrees Celsius was accomplished with the help of a dynamic light scattering method. It was determined that three types of aggregates are realized in the solutions. The average number of ... molecules in smaller aggregates and all types of aggregates were calculated. One can see that over the whole concentration range, from 0.01 to 10 g/dm3, aqueous solutions of ... are characterized by submicroheterogeneous behavior (because secondtype aggregates with the linear dimensions -- hundreds of nm are formed in all solutions). Additionally, the most concentrated solution (C = 10 g/dm3) is characterized by microheterogeneous or colloid behavior (because thirdtype aggregates with the linear dimensions on the order of ... are formed). In order to describe or explain such behavior, a stepwise aggregation model was invoked. (ProQuest: ... denotes formulae/symbols omitted.)
