Determination of molecular weight of polyethylene glycol using size-exclusion chromatography with multi-angle laser lightscattering and acid–base titration
Size-exclusion chromatography with multi-angle laser light scattering (SEC-MALLS) and
acid–base titration were used to determine the molecular weight of a polyethylene glycol
with low molecular weight. All potential uncertainty factors for each measurement were
evaluated using cause-effect diagrams. Weight analysis was applied to harmonize the two
different measurement results. It was fo...

Evaporation-induced aggregation of polystyrene-block-poly(acrylic acid) micelles to microcubic particles
pubs.acs.org/doi/abs/10.1021/la034300g
An evaporation-induced method for aggregation of polystyrene-block-poly(acrylic acid) (PS-b-PAA) micelles to unusual polymeric microcubic particles is reported. PS-b-PAA self-assembles into spherical nanomicelles in the block-selective solvent water. After addition of butanone, 1-propanol, acetic acid, N,N-dimethylformamide (DMF), or n-butylamine, evaporatio...

Formation of flower-like aggregates from assembly of single polystyrene-b-poly(acrylic acid) micelles
pubs.rsc.org/en/Content/ArticleLanding/2004/NJ/b400445k
Amphiphilic block copolymer polystyrene-block-polyacrylic acid (PS-b-PAA) self-assembles into spherical core-shell micelles in the block-selective solvent water with the PS block as the core and the PAA block as the shell. When adding 1-propanol to the micellar solution and then casting the micellar solution at suitable temperatures, the sph...

Adsorption of poly(4-vinyl pyridine) unimers into polystyrene-block-poly(acrylic acid) micelles in ethanol due to hydrogen bonding
pubs.acs.org/doi/abs/10.1021/ma0499775
The adsorption of poly(4-vinyl pyridine) (P4VP) unimers into spherical core−shell micelles self-assembled by polystyrene-block-poly(acrylic acid) (PS200-b-PAA78) in ethanol is studied by a combination of static light scattering (SLS) and dynamic light scattering (DLS). P4VP unimers with a coil size of ca. 7.9 nm can be first absorbed into the PS-b-PAA ...

Comicellization of poly(ethylene glycol)-block-poly(acrylic acid) and poly(4-vinylpyridine) in ethanol
pubs.acs.org/doi/abs/10.1021/ma0478761
Comicellization of poly(4-vinylpyridine) and poly(ethylene glycol)-block-poly(acrylic acid) in ethanol is studied by static light scattering (SLS), dynamic light scattering (DLS), and scanning electron microscopy (SEM). It is found comicellization takes place due to strong hydrogen bonding between poly(4-vinylpyridine) and the poly(acrylic acid) block when m...

Adsorption of the thermoresponsive copolymer of poly(N-isopropylacrylamide-co-4-vinylpyridine) (PNIPAM-co-P4VP) onto the core–shell microspheres of poly(styrene-co-methylacrylic acid) (PS-co-PMAA) is studied. The core–shell PS-co-PMAA microspheres are synthesized by one-stage soap-free polymerization in water. The copolymer o...
