Polymer deriving from nature as Chitosan, which is one of the most abundant natural polymers in world has effectively antibacterial potentiality. However, chitosan relatively difficult for applications due to its disadvantageous properties. In this article, modifying (CS) grafting copolymerization using monomer n-butyl acrylate (BA) and tert-butyl hydroperoxide (TBHP) an initiator. This process purposes attain product having lower glass transition temperature (Tg) than original causing a wide range but still keeping capability being excellently agent. The effects parameters on synthesizing copolymer were studied by determining percentage (G%) efficiency (E%). results revealed that highest G = 242% E 61% obtained at conditions following: BA/CS 4 w/w, TBHP/CS 5 v/w with [TBHP] 20mM, [CS] 0.75% w/v acetic acid 0.6% reaction 90°C 6 hours.
