Abstract：Hyperbranched poly (methyl ot-bro-moacrylate) was prepared by a one-pot atomtransfer radical polymerization. The polymerizationprocess was tracked by FrIR. The ratio of the areaof C=C to that of C=O of the sample gave theconversion of the monomer. The structures of thehyperbranched polymers were confirmed by thetri-detector SEC, 1H-NMR and element analysis.
