Graft efficiency
WebThe above phenomenon caused hindrance in normal graft copolymerization by restricting the movement of free radicals resulting in a less efficient initiation process and grafting efficiency (Ogbeifun and Okieimen, 2004; Pandey and Mishra, 2011; Maia et al., 2012). Finally, the amount of monomer and polysaccharides were reduced to optimum ... WebOct 1, 2012 · Final values of graft percentage and graft efficiency were the same for both methods, although the speed in reaching these values varies from one technique to another. The graft/reaction time percentage was found to be inversely proportional to intrinsic viscosity/molecular weight, likely due to main chain degradation promoted by KPS.
