EOR (Enhanced Oil Recovery) can be used to improve the petroleum productivity. One of the methods used for EOR is polymer injection. In this research, the polymer was <br /> <br /> <br /> <br /> <br /> <br /> <br /> synthesized by utilizing shrimp shell waste. It contains chitin that can be obtained by deproteinization and demineralization process. Chitosan can be synthesized from chitin by deacetylation process. In this work, the degree of deacetylation of 79% was found using FTIR spectrum. Chitosan’s average molecular mass obtained from viscometry method was 9.86&#1093;105 g/mol. Chitosan was then copolymerized with acrylamide using microwaveinitiated-grafting method without the use of any free radical initiator. The exposure time for this microwave initiated copolymerization was 1.5 minutes, while the microwave power used was 800 W. The functional groups of chitosan-graft-acrylamide (Ch-g-AM) were analyzed by FTIR. Furthermore, the intrinsic viscosity and dynamic viscosity were measured. It was found that the most optimum acrylamide’s concentration giving the highest % grafting and intrinsic viscosity was 2.0 M. The value of % grafting and intrinsic viscosity were 809.34% and 2370 mL/g, respectively. The rheological properties of Ch-g-AM were measured by viscometer Fann VG. It showed that the Ch-g-AM had a higher resistance to temperature and salinity than the commercial polymer called HYBO. However, it took higher concentration to achieve the same viscosity value as HYBO.
