Various types of hydrogen bonds, their temperature dependence and water-polymer interaction in hydrated poly(acrylic acid) as revealed by H-1 solid-state NMR spectroscopy
Various types of hydrogen bonds, their temperature dependence and water-polymer interaction in hydrated poly(acrylic acid) (PAA) were systematically investigated using 1H CRAMPS solid-state NMR techniques in the temperature range from 25 to 110 °C. The 1H CRAMPS NMR methods are based on a recently developed continuous phase modulation technique for 1H-1H homonuclear dipolar decoupling. The 1H CRA...

Unimacromolucule exchange between bimodal micelles self-assembled by polystyrene-block-poly(acrylic acid) and polystyrene-block-poly(amino propylene-glycol methacrylate) in water
pubs.acs.org/doi/abs/10.1021/jp036355x
Unimacromolucule exchange between bimodal star micelles self-assembled by polystyrene-block-poly(acrylic acid) and polystyrene-block-poly(amino propylene-glycol methacrylate) in water has been studied by laser light scattering. Unimacromolucule exchange can take place in the mixture of the bimodal star micelle aqueous solution at 25 °C. Increasing temper...

Core-shell-corona micellar complexes between poly(ethylene glycol)-block-poly(4-vinyl pyridine) and polystyrene-block-poly(acrylic acid)
onlinelibrary.wiley.com/doi/10.1002/macp.200500368/abstract
The complexation between polystyrene-block-poly(acrylic acid) (PS-b-PAA) micelles and poly(ethylene glycol)-block-poly(4-vinyl pyridine) (PEG-b-P4VP) is studied and a facile strategy is proposed to prepare three-layered core–shell–corona micellar complexes. Micellization of PS-b-PAA in ethanol gives rise to spherical core&nda...

Synthesis of porous poly(styrene-co-acrylic acid) microspheres through one-step soap-free emulsion polymerization: Whys and wherefores
www.sciencedirect.com/science/article/pii/S0021979711013920
Synthesis of porous poly(styrene-co-acrylic acid) (PS-co-PAA) microspheres through one-step soap-free emulsion polymerization is reported. Various porous PS-co-PAA microspheres with the particle size ranging from 150 to 240 nm and with the pore size ranging from 4 to 25 nm are fabricated. The porous structure of the microspheres is confi...

Effect of Acrylic Acid and Hydroxyethyl Methacrylate Modified Nano-SiO2 Particles on Poly(Methyl methacrylate-HEMA) Soap-free Emulsion Polymerization
Nano-SiO2 powder was modified with acrylic acid (AA) and hydroxyethyl methacrylate (HEMA), respectively. The kinetics of the soap-free emulsion polymerization of methyl methacrylate (MMA) and HEMA in the presence of unmodified or modified nano-SiO2 particles was investigated. The structure of the nano-SiO2 particles and the Poly(MMA-HEMA) composite emulsion was characterized by Fourier transform i...

Polymer 2011:Fabrication and stability of porous poly(allylamine) hydrochloride (PAH)/poly(acrylic acid) (PAA) multilayered films via a cleavable-polycation template
Porous films were fabricated from nonporous layer-by-layer multilayers composed of a blend of positively charged disulfide-containing polyamidoamine and poly(allylamine hydrochoride), and negatively charged poly(acrylic acid), followed by removal of cleavable disulfide-containing polycation after incubation in 1 mM DTT solution. The thickness of original multilayered films decreased with the incre...
