Özet:

 

A novel method based on steady state fluorescence  measurements is introduced for measuring the activation energy of the  number average degree of polymerization (NADP).  Pyrene (Py) was used  as a fluorescence probe for real time monitoring of free-radical  polymerization (FRP) of methyl methacrylate (MMA).  In situ FRP  experiments were performed at various temperatures.  Positive  activation energy for NADP was measured and found to be 9.2 kcal/mol.
