Mechanical property studies of poly(methyl methacrylate)-grafted viscose fibers

摘要

Graft copolymerization of methyl methacrylate (MMA) on viscose fibers (grade 1.5 x 51 mm; Nagda; grey staple; bright bleached) was studied under a photoactive condition with visible light using conventional Mohr's salt-potassium persulphate as the redox initiator. The mechanical properties of the grafted viscose fiber, such as tenacity, breaking extension, and initial modulus were studied. The effect of monomer-solvent combination on viscoelastic nature (elasticity work recovery and stress relaxation) of the grafted fibers have also been explained. The moisture regain characteristics of the grafted fibers were also studied, (C) 1998 John Wiley & Sons, Inc. [References: 20]
