“…To characterize the extent and efficiency of the grafting reaction, parameters like add-on and grafting efficiency (GE) are commonly used (Athawale & Rathi, 1999;Park, Song, & Song, 1999;Patil & Fanta, 1993;Vera-Pacheco, Vázquez-Torres, & Canché-Escamilla, 1993). Add-on depicts the weight ratio of the grafted polymer to the total grafted product.…”
