“…However, starch by itself is unsuitable for most uses as a plastic, because of its poor physical properties (mechanical properties, dimensional stability). Graft copolymerization is one of the efficient methods to modify natural [1][2][3] and synthetic polymers. 4 -6 In this way, it is possible to modify many different properties in the starch, such as elasticity, sorbancy, ion-exchange capabilities, thermal resistance, and resistance to microbiological attack.…”

Radiation-induced graft copolymerization of maize starch/acrylic acid has been performed. Also, natural byproduct wood pulp was used after chemical treatment for the removal of metal ions from the investigated wastewater. The surface and structure morphology of the wood pulp and starch/acrylic acid were investigated by scanning electron microscopy and infrared spectroscopy. The physical parameters, such as swelling, gel percentage, and grafting efficiency (%) of starch/acrylic acid copolymer, were studied. The factors affecting the abilities of the prepared materials for removing heavy metal ions and dyes from aqueous solutions were studied. It was found that the maximum metal uptake is in the following sequence: Fe 3ϩ Ͼ Cr 3ϩ Ͼ Pb 2ϩ Ͼ Cd 2ϩ . The adsorption capacity of such investigated metal ions increases with the increase of pH values.

“…At higher graft yield values, the decomposition temperature of polyMAA‐grafted acrylic fibers was observed to increase. This indicates that grafting increases the thermal stability of acrylic fibers perhaps due to new crosslinkages formed after grafting 15, 18…”

“…An increase in monomer concentration increases the number of MAA molecules diffused into acrylic fibers. This increases the probability of acrylic macroradicals and growing grafted side chains to find monomer units to add and, therefore, increases the graft yield 3, 14, 15…”

Acrylic fibers were graft copolymerized with methacrylamide in aqueous media, using benzoyl peroxide as a free-radical initiator. The grafting reactions were carried out within the 75-95°C temperature range, and the effect of initiator, monomer concentrations, and the amount of fiber on the graft yield were also investigated. The maximum graft yield was reached at the benzoyl peroxide concentration of 3.0 ϫ 10 Ϫ3 mol/L and the optimum temperature of 85°C. The activation energy of the reaction was found to be 33.8 kcal/mol at the temperature interval of 80 -95°C. The grafted fibers were characterized with infrared spectroscopy, scanning electron microscopy, and thermogravimetry.The thermogravimetric analysis results revealed that the degradation temperature of the acrylic fibers increased with grafting. The scanning electron photographs showed that the homogeneous appearance of the fiber surface changed and a shell-like heterogeneous structure occurred at the surface with an increasing degree of grafting. The moisture content and water absorption of grafted acrylic fibers was highly enhanced by grafting.
