Block copolymer vesicles, or polymersomes, are of continued interest for their ability to encapsulate aqueous compartments within relatively robust polymer bilayer shells (Fig. 7) [66, 67]. Eisenberg and coworkers were the first to report the formation of block copolymer vesicles from the self-assembly of polystyrene-h-poly(acrylic acid) (PS-h-PAA) block copolymers. They also have described the formation of a wide range of vesicle architectures in solution from the self-assembly of five different block copolymers PS-h-PAA. PS-h-PMMA, PB-h-PAA, polystyrene-h-poly(4-vinyIpyridinium methyl iodide), and polystyrene-h-(4-vinylpyridinium decyl iodide) [68]. Small uniform vesicles, large polydisperse vesicles, entrapped vesicles, hollow concentric vesicles, onions, and vesicles with hollow tubes in the walls have been observed and the formation mechanism discussed. Since vesicles could be prepared with low glass transition polymers such as PB [69, 70] and PPO [71], it has been established than these structures are thermodynamically stable and not trapped by the glassy nature of the hydrophobic part. [Pg.175]

While simple homopolymers and random copolymers exhibit single, sharp glass transitions, polymer blends in general, and IPN s in particular, show two such transitions, one for each phase. The intensity of each transition is clearly related to the overall composition and phase continuity, while shifts and broadening of the transition indicate the extent of molecular mixing. In contrast, electron microscopy (previous section) shows phase size... [Pg.246]

At the lowest temperature, the primary and secondary relaxations are separating. The long-time part of the gamma relaxation is visible in the short time window of the technique.
