The preparation of poly(methyl methacrylate)-b-polyacrylamide(PMMA-b-PAAM) using 4,4'-azobis[4-cyanopentanoyl(p-dimethyl amino) anilide](ACPDA) as an initiator was investigated. At 70℃, ACPDA initiated methyl methacrylate(MMA) to give a PMMA prepolymer containing N,N dimethyl anilide terminal group(DMA). The redox system of the PMMA/benzoyl peroxide(BPO) could initiate the polymerization of acrylamide(AAM) to give PMMA-b-PAAM. The block copolymer was characterized by IR, TG, DTA, PGC and SEM. The PMMA-b-PAAM showed a better thermal stability than PMMA homopolymer.
