Synthesis and Characterization of a Bifunctional Initiator Containing Azo Bond and Aromatic Amine Group

A bifunctional initiator 4,4'-azobis(4-cynopentanoyl(p-diethyl-amino)anilide)(ACPEA) was synthesized by 4,4'-azobis(4-cyanopentanoic acid)(ACPA) and 4-amino-N,N-diethylaniline,its structure was confirmed by elemental analysis,IR and 1H-NMR.The polymerization of methyl methacrylate(MMA) initiated by ACPEA in N,N-dimethyl formamide was studied.The results show that MMA can be initiated by ACPEA to produce poly(methyl methacrylate)(PMMA).The molecular weight increases with increasing the concentration of monomer.The molecular weight decreases with increasing the concentration of ACPDA and the reaction temperature.
