Thermal behaviour of methylmethacrylate-grafted viscose fibres

摘要

Graft copolymerization of methyl methacrylate on viscose fibre has been done using titanium(III) chloride-potassium persulphate redox initiator under visible light in limited aqueous system in presence of various solvents and grafted polymers have been characterized by DSC and TGA. The DSC results show a low compatibility in the thermal properties of viscose fibre and PMMA. The role of pendant PMMA chain produced in presence of different solvents and the thermal stability of graft copolymers have been analyzed by TGA study.
