Abstract
The steady-state fluorescence (SSF) technique was used to study the polymer ization rate in free-radical crosslinking copolymerization (FCC) of methyl methacrylate (MMA) and ethylene glycol dimethacrylate (EGDM). Pyrene (Py) w as used as a fluorescent probe for the in situ polymerization experiments. The increase in Py intensity was monitored during FCC. The Stern-Volmer kin etic was employed to determine the MMA consumption rate during gelation pro cess for various EGDM contents and at different temperatures. (C) 2001 John Wiley & Sons, Inc.
