Notes:
The thermal decomposition rate constant of AIBN (kd) in N,N-dimethylformamide (DMF)/methyl methacrylate (MM) mixtures of various compositions at 60°C is studied. The kd value is 6.45 × 10-4min-1 for pure DMF and 7.20 × 10-1 min-1 for pure methyl methacrylate. The kd values of DMF/MM mixtures were found to be dependent on the mixture composition. This dependence is not a linear function of the monomer mole fraction, but has a minimum at ca. 20 30 mol% of MM. The relationship between the AIBN decomposition rate constant and the monomer mole fraction was interpreted on the basis of solvation of the initiator molecules. © 1995 John Wiley & Sons, Inc.
