2-Bromomaleic anhydride (BrMAn) and styrene (St) were found to make a charge-transfer complex at a 1 : 1 ratio. The copolymerization followed the generalized mechanism for alternating copolymerization, and an alternating copolymer was obtained over a relatively wide feed composition range. The monomer reactivity ratios, rBrMAn and rSt, were found to be 0 and 0.05, respectively, at 60°C. The copoly(BrMAn/St) was dehydrobrominated by heating under reduced pressure and a polymer with a structure similar to the maleic anhydride moiety in the polymer chain was obtained. The dehydrobromination was completed by heating at 190°C for 1 h.
