Abstract: | Highly diluted solutions of an alkaline treated pig bone gelatin and a seaweed alginate of Macrocystis pyrifera have been investigated by means of static light scattering at various temperatures. With these results the thermodynamic properties found by other authors and us before can be verified. Furthermore, diluted mixtures of both polymers with different ratios of composition have been investigated. These measurements show that both polymers in all mixtures behave quasi-binarily in the investigated temperature range. They maintain their association phenomena of the pure polymer solutions. |
