Superabsorbent hydrogels are polymers with a 3D network that have attracted the attention of scientists and industrialists because of their fantastic ability to absorb and retain water and aqueous solutions. The most widely used and commercially available... see more

Thermal decomposition of the copolymer of polyethylene glycol fumarate with acrylic acid (p-EGF:AA) of two different compositions synthesized earlier was studied in the present work. TG and DTG curves prove that decomposition takes place in several stages... see more

Reaction kinetics for the oxidation of propane over diluted-leached MoVTeNb is described. This paper is focused on the study of determination of the orders of carbon dioxide, acetic acid and acrylic acid formation. Deep oxidation of propane to carbon diox... see more

Modification of poly (acrylamide-co-acrylic acid) superabsorbent hydrogels with varying starch concentration (1-3%) via simultaneous gamma radiation have been carried out. The structure and morphology of copolymers were characterization by Fourier transfo... see more

In this study, high density polyethylene (PE) film (thickness 80 µm) was modified by grafting of acrylic acid (AA) onto the film using 15 kGy of g irradiation as initiator, applied at different exposure times. In addition to irradiation dose, other variab... see more

A series of superabsorbent hydrogels were synthesized from partially neutralized acrylic acid with varying degree of neutralization (0-1) using gamma radiation. The effects of degree neutralization of acrylic acid on swelling ratio were studied. DSC measu... see more

Starch is a renewable natural polymer that can be decomposed easily in the environment and can be modified to various applications such as biomedical, agricultural and pharmaceutical applications. Copolymerization of gelatinized starch–CM-chitosan and acr... see more

Quantitative composition of organometallic electrodeposit obtained from the solution of 0.1 M CuSO4, 1.0 M H2SO4 and 0.2 M acrylic acid was determined by differential photometry. It was shown that the deposit contains copper complexes in an amount of 15% ... see more

Based on the results of X-ray diffraction analysis it has been ascertained that cathodic copper deposit precipitated from sulfate electrolyte with acrylic acid or acrylamide consist of copper crystals with considerable quantity of imperfections and crysta... see more
