Study on Photoinitiated Cationic Polymerization Ⅲ.DSC Study on Photopolymerization of Epoxides Initiated with Sulfonium Salt BDS
Abstract:
The photopolymerization of phenylglycidylether (PGE) and an epoxy resin (E-51) initiated by bis-[4-(diphenylsulfonio) phenyl]sulfide-bis-hexafluorophosphate[BDS(PF6)2] has been studied using a modified home-made CDR-1 model differential scanning calorimeter.For PGE,the polymerization rate was proportional to the 0.90 power of the initiator concentration and to the 0.87 power of the light intensity.For E-51,the polymerization rate was proportional to the 0.78 power of the initiator concentration,whereas the influence of light intensity was rather complicated.The polymerization rate increased with temperature markedly at≤70℃(for PGE) or≤80℃(for E-51).PGE as a reactive diluent greatly in-creased the polymerization rate of E-51.
