micelle

 The influence of the structure of macromolecular chain of aminofunctional polyesters of pseudo-polyamino acid on the value of their surface active properties is established. Pseudo- polyamino acids with the regular alternation of hydrophilic and lipophilic fragments in macromolecule’s structure have the highest ability to decrease the surface tension of their water dispersions. The pseudo-polyamino acid macromolecules at near CCM concentration form the stable micellar structures in water medium. Such micellar structures can be used for construction of polymer drug delivery systems.

Physicochemical and tribological properties of overbased phenolate lubricating greases were studied in the comparison with analogous sulfonate and alkylsalicylate greases. Overbased components were extracted from the grease model systems and also researched. The scheme and parameters of the real micelles’ carbonate nuclei are discussed.
