Application Polystyrene-block-polyacrylic acid is a diblock copolymer used for making polymeric micelles/vesicles (polymersomes) and other encapsulation applications,. This PS-block-PAA copolymer is 20 wt. % AA; and should form micelles in water in the 30~50 nm range. The polystyrene degree of polymerization (DP) is 275 and the polyacrylic acid DP is 120.
