“…Fascinating morphologies on the molecules with somewhat more complex architectures have also been found turn by turn. For example, ball‐in‐a‐box structure,11 wagon‐wheel type structure,12 superlattice structures,13 non‐constant mean curvature morphology,14 a variety of hierarchical morphologies,15, 16 a core‐shell gyroid structure17 have been observed experimentally for linear three‐component triblock copolymers of the ABC type, while several complex structures were predicted by theoretical approaches for the same type of molecules 18, 19. Furthermore, non‐centrosymmetric structures were reported for more complex systems such as an ABC/AC blend20 and an ABCA tetrablock terpolymer 21.…”

Among several star molecules studied so far, the results for two similar but slightly different systems composed of all hydrophobic components, i.e. one low T(g) arm and two high T(g) arms were compared and discussed mainly. They are polyisoprene-arm-polystyrene-arm-poly(2-vinylpyridine) stars and polystyrene-arm-polybutadiene-arm-poly(2-vinylpyridine) ones, and are abbreviated as ISP and SBV, respectively, in the original literatures. Several periodic Archimedean tiling patterns can be naturally formed when the relative lengths of three chains are similar one another in both series. Core-shell type morphologies and actually three-phase four layer lamellar structures were also commonly observed for two series. A quasicrystalline tiling with dodecagonal symmetry can also be conformed at the targeted composition of ISP/homopolymer blend and a zinc-blende type structure was created at just a little outside of tiling region for the same blend. Furthermore, the several interesting structures from amphiphilic molecules, composed of a hydrophilic component, poly(ethylene oxide), a hydrophobic component, polymethylmethacrylate and a highly water-repellent polymer poly(perfluoropropyleneoxide) are described and introduced.

ABSTRACT:The polymers of three tertiary aminostyrenes: poly(N,N-dimethyl-4-vinylphenylamine), abbreviated as PPA; poly(N,N-dimethyl-4-vinylbenzylamine), PBA; and poly-(N,N-dimethyl-4-vinylphenethylamine), PPTA, were prepared via anionic polymerization in THF at -78°C. GPC measurement was carried out to estimate the molecular weights and molecular weight distributions (MWD) of the polymers. A mixture of THF and Nmethylpyrrolidine (2 v/v%) was used as carrier solvent to avoid the adsorption of the polymers on the surface of the GPC gels. When n-butyllithium was used as an initiator, 100% polymer conversion was attained. The values of Mw/Mn were more than 1.20. The M. was equal to Mk, calculated from the amounts of monomers and initiators. No polymer having narrow MWD was obtained, even when N-methylpyrrolidine was used as an additive. On the other hand, when cumyl potassium and cumyl cesium were used as initiators, polymers having narrow MWD were produced. The values of M w! Mn were less than 1.08. The apparent rate constant of polymerization of cumyl cesium for PPA was small, compared with those for PBA and PPT A.

“…Ternary (ABC) triblock copolymers have been in the centre of research during the last three decades [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] . This became possible by improvements in the polymerization techniques, which gave access to well defined materials with low polydispersities.…”
