Abstract
Abstract The r esearch of grafting methyl methacrylate (MMA) on to Cyclic Natural Rubber (CNR) has been carried out. Benzoyl Peroxide (BPO) was used as a inisiator and temperature condition at 90 o C with variation of time 1 and 2 hour s . Grafting p rocess was done with technique of reflux in a tree-neck flask with condenser and oil bath. Spectra analysis FTIR performed for determine the presence of graft ed MMA on the backbone of CNR. The results showed that the product CNR-g-MMA was formed with the marked appearance of the absorption peak wave numbers at 1731 and 1730 cm-1 (carbonyl group absorption) typical for carbonyl (C = O) of metal methacrylate. The degree of grafting increased with the increasing time grafting. Keywords: grafting, cyclic natural rubber, mathylmetacrilate, benzoyl peroxide
