“…The water absorption values of grafted acrylic fibers increased within an initial narrow range of graft yield (0–80%), thereafter decreasing very slowly due to the grafting process blocking the water attracting groups on the acrylic fiber chains4 (Fig. 10).…”

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.

“…Graft copolymerization is a well‐established technique used to modify properties of natural1–4 and synthetic polymers 5–9. In this way, it is also possible to modify many different properties in the fibers, such as dyeability, ability to handle, thermal and chemical resistance, wash and wear characteristics, etc.…”

Soy protein concentrate was grafted with ethylmethacrylate using ascorbic acid/potassium persulphate as a redox initiator. Different reaction parameters, such as reaction time, reaction temperature, solvent amount, initiator ratio, and pH, and monomer concentration were optimized to get maximum graft yield (134.12%). The graft copolymer formed was characterized by Fourier transform infrared spectrophotometer, X-ray diffraction, and scanning electron microscope techniques. Thermogravimetric analysis, differential thermal analysis, and differential thermogravimetric analysis studies showed that graft copolymer was thermally more stable than the backbone. Thermal decomposition studies indicated that the rate of weight loss per minute was found more in case of backbone when compared with that of graft copolymer. Further, graft copolymer was also found more resistant toward acid-base attack and was found to be more water repellent.
