Experimental and Theoretical Modeling of Runaway Polymerization Under Free-radical Initiation

摘要

This paper presents an experimental study of runaway polymerization of some common acrylic and vinyl monomers using the VSP2 adiabatic calorimeter. These monomers include methyl methacrylate, butyl acrylate, methyl acrylate, ethyl acrylate, vinyl acetate, vinyl pyrrolidinone and styrene. The free-radical initiators consisted of azo type and organic peroxide type. Modeling of the runaway self-heating behavior is attempted based on the classical free-radical polymerization kinetics. Comparison between model predictions and experimental data are shown to yield good results for many monomer systems, however, some deviations are noted.
