Gum Arabic (GA) collected from Acacia senegal trees was used with polyvinyl alcohol (PVA) to prepare of a series of biodegradable membranes doped and non-doped with potassium dichromate (K 2 Cr 2 O 7 ). Adding the K 2 Cr 2 O 7 to the GA/PVA blends slightly decreased their crystallinity index (CI) by about 2 %. Increasing the PVA concentration in the chromated GA/PVA blends was responsible for increasing the CI. Adding the K 2 Cr 2 O 7 to the pure GA solution modified its differential thermal behavior whereby the exothermic reactions occurred between 321°C and 433°C were disappeared. The K 2 Cr 2 O 7 increased the heat change drastically for all the bioplastic blends with the highest increase for the pure GA. Adding K 2 Cr 2 O 7 to the pure PVA increased the nanometric particle size (NPS) significantly. Increasing the PVA concentration in a blend had a greater effect than did the K 2 Cr 2 O 7 on the NPS. The buried bioplastic membranes in the control soil had different count and species of microbial communities. The numbers of bacteria and fungi in the initial soil sample were lower than those for chromated GA membranes and were greater than those for the chromated PVA. All bacterial and fungi species had growth ability and are expected to be detoxification tools of chromium ion-doped blends of GA and PVA leading to a green environment.

“…In semicrystalline polymers, some of their macromolecules are arranged as crystallites immersed in an amorphous matrix. The greater the concentration of these crystallites, the greater the crystallinity and subsequently more rigidity were obtained for the polymer [3].…”

“…Previously the method for quantitative determination of styrene in the IR spectra of solutions of styrene-containing of polymers was described [3]. The analysis is based on the integration of characteristic absorption bands in the region 694 cm -1 and the final calculation of the mass fraction of styrene in the sample.…”

“…However, some researchers have noted that the saponification is subjected to only a part of the ester groups [3] and in addition in this method there are restrictions from the point of view of solubility of the analyzed polymers, the formation of precipitations in the process of titration and, as a consequence, the low reliability of the results.…”

“…Однако не-которые исследователи отмечают, что омылению подвергается только часть сложноэфирных групп [3], и, кроме того, у данного метода существуют огра-ничения с точки зрения растворимости анализируемых полимеров, образова-ния осадков в процессе титрования и, как следствие, низкой достоверности результатов.…”

Identification of the monomeric composition of poly(styrene)acrylatesThe work is devoted to qualitative analysis of poly(styrene)acrylates, the definition of the content of styrene in them. The methods of IR, NMR spectroscopy and gas chromatography-mass spectrometry were used for analysis. It was shown that the integrated use of modern spectral methods allows unambiguous to lead identification of the components in the copolymer and to use of spectral data for quantitative determinations. Идентификация мономерного состава поли(стирол)акрилатовРабота посвящена качественному анализу полистиролакрилатов, определению содержа-ния в них стирола. Для проведения анализа были использованы методы ИК-, ЯМР-спектро-скопии и газовой хромато-масс-спектрометрии. Было показано, что комплексное использо-вание современных спектральных методов позволяет однозначно провести идентификацию компонентов в сополимере, а также использовать спектральные данные для количественных определений.Ключевые слова: поли(стирол)акрилаты; современные спектральные методы; термоде-струкция; база данных; програмное обеспечение.
