Abstract
A series of well-defined acrylamide/methyl methacrylate random copolymers (PAM-ran-PMMA) were synthesized in this work. The polymerization reactions were carried out in N,N-dimethylformamide (DMF) at 25 °C using Cu(0)/hexamethylenetetramine (HMTA) and CCl4/hydrazine as the catalyst system and the initiator system, respectively. The number average molecular weights (Mn) and the distribution of molecular weight (Mw/Mn) of copolymers were analyzed by gel permeation chromatography (GPC). Experimental results revealed that the copolymerization reaction follows a pseudo first-order kinetic model. Mn of PAM-ran-PMMA increased linearly with the conversion of monomers while a narrow molecular weight distribution was obtained. By means of Fineman–Ross equation, the reactivity ratios of r1 (AM) and r2 (MMA) were calculated to be 0.81 and 3.21, respectively. The results implied that the amount of AM unites in PAM-ran-PMMA copolymers increased with the increase of the molar ratios of AM/MMA. The structure and the thermal stability of the resultant PAM-ran-PMMA copolymer were characterized by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectrometry (1H NMR) and thermogravimetric analysis (TGA). TGA revealed that copolymers with a greater content of AM unit exhibited a higher thermal stability. The obtained PAM-ran-PMMA copolymer was used as a macroinitiator to perform Cu(0)-catalyzed chain extension experiment, which led to the increase of Mn and demonstrated the living character of the polymerization. This current approach provided a controlled route for the synthesis of well-defined PAM-ran-PMMA.
