Evidence for two gel effects during the bulk polymerization of ethyl acrylate from DSC, Rayleigh and brillouin scattering
- 67 Downloads
DSC studies of the bulk polymerization of ethyl acrylate have revealed the occurrence of irregular kinetic behaviour during the initial stage of the reaction at less than 5 per cent monomer conversion. Simultaneously, a maximum in the 90° Rayleigh scattering was observed. The transient inhomogeneity and the shoulders on the rate-time curves are attributed to a localized gel effect which precedes the general gel effect.
