The use of p,α-dimethylstyrene, potentially obtainable from renewable sources, as a substitute for styrene in the synthesis amphiphilic copolymers is reported this work. A series novel poly(p,α-dimethylstyrene-co-maleic anhydride) (SMA) was synthesized, characterized, and studied potential polymeric surfactants. After hydrolysis, solution properties were compared to similar very well-known styr...

N-Ethylmaleimide and maleic anhydride add to the interior face of one anthracene wall with unusual 1,4-regioselectivity, whereas singlet oxygen adds to both anthracene walls with 9,10-regioselectivity.

The chemical modification of wood can be directed to improve various properties, e.g., the dimensional stability, hardness and/or durability against weathering. In this study, a Romanian softwood species Abies alba Mill. was treated and chemically modified using two cyclic acid anhydrides, i.e., maleic succinic, its interfacial properties relative unmodified wood. Structural changes, with focus...

The effect of residual lignin content on the mechanical strength and water absorption of kraft pulp/ polypropylene composites was studied. To meet this objective, hornbeam wood chips were converted to kraft pulp at three different alkalinities (15, 20, and 25%) and three different cooking times (60, 90, and 120 min). The residual lignin contents of these pulps were determined according to the T...

This study focuses on the development of low-density polyethylene matrix nanocomposite films for food packaging industry and aims at improving oxygen barrier properties while maintaining other relevant characteristics, such as processability, easy post-processing, optical mechanical properties. nanocomposites, with 1 2.5 wt.% nanoclay (NC) also compatibilized 5 grafted maleic anhydride (PE-g-MA...

Pteris vittata is a hyperaccumulator fern able to uptake arsenic by roots accumulating it in the fronds. Recent studies showed that can be used efficiently for arsenic-contaminated water treatment, paving way long-lasting decontamination strategies established on nature-based solutions. This raises issue of biomass disposal, which rather than being incinerated could represent valuable untapped ...

Our research focuses on the characterization of the association and the properties in aqueous solution of nanostructures, particularly on nanotubes composed of amphiphilic alternating copolymers. These copolymers constitute a pH sensitive hydrophilic group (maleic anhydride) alternating with a hydrophobic group. To investigate the role of the nature of the hydrophobic groups on the association,...
