Abstract

Grafting of binary mixtures of methyl methacrylate and some vinyl monomers onto mulberry silk fibre: Synthesis, characterization and preliminary investigations into gentian violet uptake by graft copolymers

Sunil Kumar Banyal, Balbir Singh Kaith, Rajeev Kr. Sharma

Mulberry silk fibre was graft copolymerized with binary mixtures of acrylic acid, methyl acrylate and acrylonitrile with methyl methacrylate as the principal monomer in aqueous medium by using CAN as redox initiator. The binary vinyl monomers were graft copolymerized by using the grafting conditions like reaction time, temperature, concentration of MMA and CAN as reported earlier for optimum percent grafting (74.40) of MMA alone onto the same backbone. Graft copolymers were characterized by FTIR, SEM, swelling studies, moisture absorbance and chemical resistance in acidic and alkaline medium. Dye uptake (Gentian violet) on graft copolymers were studied photo-calorimetrically at 420 nm. The dying capability of the graft copolymers with binary mixture is more than the reference graft copolymer of methyl methacrylate.
