Description Polystyrene-block-polyacrylic acid is a diblock copolymer.

Application Polystyrene-block-polyacrylic acid is a diblock copolymer used for making polymeric vesicles (polymersomes) and other encapsulation applications.1-9 This PS-block-PAA copolymer is 15 wt. % AA; and should form vesicles in water in the 100 nm range. The polystyrene degree of polymerization (DP) is 275 and the polyacrylic acid DP is 50.

Features And Benefits Good biocompatibility;
Properties can be easily modulated by changing the block copolymer segment sizes to suit a particular application.
