Int J Biol Macromol. 2013 Oct:61:121-6. doi: 10.1016/j.ijbiomac.2013.06.045. Epub 2013 Jul 2.

Abstract

Rising environmental awareness has resulted in a renewed interest in biological macromolecules obtained from renewable resources. So in view of technological significance of natural lignocellulosic polymers in numerous applications, the present study is an attempt to synthesize lignocellulosic polymers based graft copolymers using free radical polymerization. Different reaction conditions have been studied to synthesize the lignocellulosic graft copolymers. The graft copolymers have been characterized with scanning electron micrography (SEM), Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The grafted samples have also been screened against different physico-chemical conditions to assess their applicability in different applications.

Keywords: Graft copolymerization; Lignocellulosic polymers; Morphological and physico-chemical characterization; Thermal.
