The complexation properties of N-phenylmaleimide (NPMI) and p-(chloromethyl)styrene (PCMS) were studied by 1H NMR in CDCl3 firstly. Novel hyperbranched alternating copolymers were successfully synthesized via living controllable radical copolymerization of the charge transfer complex made from NPMI and PCMS while PCMS was used as an inimer. The monomer reactivity ratios were evaluated to be rNPMI＝0.11 and rPCMS＝0.25 respectively by the Kelen-Tudos method. The resulting hyperbranched copolymers were of alternating structure when the molar fraction of NPMI was varied from 0.4 to 0.7. The glass transition temperature of such hyperbranched copolymer was increased with increasing fNPMI, indicating that the thermal stability of the copolymers had been improved with increasing NPMI. The influences of reaction conditions, such as solvent and the polymerization temperature on the copolymerization kinetics, were also studied. These hyperbranched alternating copolymers were successfully used as functional macroinitiators to synthesize the star-shaped poly(NPMI-co-PCMS)/poly(MMA) block copolymers.
