| Abstract: | Low molecular weight weight ,odorless styrene-maleic anhydride copolymer was synthesized by free radical solution copolymerization with 3-mercaptopropinic acid as chain transfer 2.2-azoisobutyronitril as initiator 1.2-dichloroethane as solvent The influences of reac- tion temperature reaction time and amount of initiator and chain transfer on copolymerization were investigated and the optimum synthe- sis conditions were build by orthogonal test method |
