Synthesis and properties of new water-soluble copolymers based on methyl acrylic acid sucrose ester and methyl acrylic acid

The antimicrobial activity of chitosan and water soluble interpolyelectrolyte complexes of poly(acrylic acid)-chitosan was studied. Chitosans of two different molecular weights were tested at different concentration for 0.5 to 5 g·L-1 as antimicrobial agents against P. aeruginosa and P. oleovorans. In both cases, the best microbial inhibition was obtained with the concentration of 5 g·L-1. However, the interpolyelectrolyte complexes of poly(acrylic acid)-chitosan with composition φ =2 produced higher antibacterial activity than the two chitosans at the concentration of 0.5 g·L-1. The NPEC2 complex was more effective than chitosans. This could be attributed to the number of moles of the amino groups of chitosan and the carboxylic acid groups of the interpolyelectrolyte complexes poly(acrylic acid).

Our objective is to improve on our previous work developing thiol-containing water-soluble copolyacrylamides that form hydrogels in situ for use as vitreous substitutes. In this study, we evaluate the incorporation of acrylic acid by varying the feed ratio of acrylic acid monomer from 0 to 40 mol% in combination with acrylamide, and bis-acryloylcystamine as the reversible cross-linker. After polymerization, the formed copolymer hydrogels were reduced with dithiothreitol to cleave the disulfide cross-linkers. Purified, lyophilized copolymers were made in a concentration range of 12.5–17.5 mg/mL (polymer in deionized water) and were gelled by oxidation. Chemical, physical, optical, and rheological characterizations along with in vitro biocompatibility studies were performed using thiazolyl blue and Electric Cell–substrate Impedance Sensing. Increasing the percentage of acrylic acid caused the polymer to gel at 12.5 mg/mL as opposed to 20 mg/mL without acrylic acid. Storage modulus values covered the range of natural vitreous (1–108 Pa). Biocompatibility testing in tissue culture with retinal pigment epithelial cells (ARPE-19) showed no toxicity at 10 mg/mL or less when compared to controls, higher concentrations. In contrast to our previously reported copolyacrylamide hydrogels, these hydrogels remain optically clear and gel at lower concentrations and have the potential for use as vitreous substitutes.

Исследована реология водных растворов полиакриловой кислоты, полиакриламида, поливинилового спирта, сополимера акриловой кислоты с акриламидом, a также смесeй водных растворов этих полимеров. В результате образования ассоциатов между функциональными группами уаказанных полимеров значительно повышается относительная вязкость их водных растворов. Установлено, что при температуре 95C в водных растворах полиакриламида и сополимера акриловой кислоты с акриламидом происходит интенсивное выделение аммиака с одновременным образованием полимера пространственной структуры. The rheology of aqueous solutions of polyacrylic acid, polyacrylamide, polyvinyl alcohol, copolymer of acrylic acid with acrylamide, as well as mixtures of aqueous solutions of these polymers was investigated. As a result of the formation of associates between the functional groups of the polymers indicated, the relative viscosity of their aqueous solutions significantly increases. It was established that at a temperature of 95°C in aqueous solutions of polyacrylamide and a copolymer of acrylic acid and acrylamide, there is an intense release of ammonia with simultaneous formation of a polymer of spatial structure.

Background Electrolytes

The effect high molecular weight water-soluble surfactants with different functional groups have on the electroreduction of lead(II) ions on a lead electrode in various electrolytes is studied. A copolymer of methacryloylaminophenol with acrylic acid, a leather waste hydrolyzate, and a copolymer of monoethanolamine with vinyl ether acetate are used as surfactants. The electrolytes that are used are 1 M KCl, KBr, KNO3, HCOONa, NH2SO3H, 0.5 M Na2SO4, and 0.35 M Na3C6H5O7 .2H2O. It is shown that in 1.0 M KCl or KBr solutions, there is no inhibition of the electroreduction of lead(II) ions by the adsorption layers of surfactants. It is found that the inhibitory effect of polymers on the electroreduction of lead(II) ions in different background electrolytes increases in the order KCl > KBr > Na3C6H5O7.2H2O > Na2SO4 > KNO3 > HCOONa > NH2SO3H. Key words: lead ions, electroreduction, surfactants, electrolyte, lead electrode, exchange current.
