Abstract

Marine oil spills are the most important threat to the coastal environment and ecosystems of the sea. Furthermore, oil spills are responsible for the great loss of energy resources. Millions of tons of oil are spilled every year, accidentally and deliberately, into the environment during transport, storage and processing of the oil. The methods commonly used to remove oil involve oil booms, dispersants, skimmers, sorbents etc. The use of sorbents is of great interest, as it allows the collection and complete removal of oil, by achieving a change from liquid to semi-solid phase. It is well known that oil sorbers should have hyDROPhobic character to swell in oil medium. So, this study involved synthesis of oil sorbent copolymers based on hyDROPhobic monomers (alkyl acrylates) and hydroxypropyl cellulose acrylate macromonomer (HPCA). Hence, hydroxypropyl cellulose acrylate (HPCA) macromonomer was prepared by the reaction of hydroxypropyl cellulose (HPC) with acryloyl chloride. The structure was elucidated using FTIR and 1HMNR analyses which explained that the esterification reaction between HPC and acryloyl chloride was successfully performed. The prepared HPCA was used to prepare three dimensional crosslinked copolymers through coagulation followed by bulk polymerization reaction. In this respect, different mole % of HPCA to different mole % of alkyl acrylate monomers [octadecyl acrylate (ODA), and/or ethylhexyl acrylate (EHA)] were individually copolymerized using azobisisobutyronitrile (AIBN) as free radical initiator and two types of crosslinkers namely, divinylbenze (DVB) and methylenebisacrylaime (MBA) to produce different crosslinked copolymers of HPCA/ODA and HPCA/EHA respectively.
