Evaluation of Morphological Transition in Advanced Materials

The reaction parameters for the graft copolymerization were optimized using an effective acrylate monomer onto Hibiscus sabdariffa (Roselle) stem fiber and used to explore the additive effect of secondary monomer on percentage grafting and change in the properties, behavior of the fiber in binary vinyl monomeric mixtures. The graft co-polymers were characterized by advanced techniques and evaluated for changes. With increase in percentage grafting there was increase in thermal resistance but decrease in percentage crystallinity and crystallinity index. However, cellulose form I remained unchanged. These modified graft copolymer procured from renewable waste biomass can have numerous scientific applications.
