The investigation of photoinitiated polymerization of multifunctional acrylates with TX-BT by Photo-DSC and RT-FTIR

Photopolymerization of multifunctional acrylates with 3H-5-Thia-1,2,3-triaza-cyclopenta[b]anthracene-10-one (TX-BT) as the one-component photoinitiator was investigated using real-time Fourier transform infrared spectroscopy (RT-FTIR). Photo-differential scanning calorimetric (Photo-DSC) technique w...

Description
Summary:Photopolymerization of multifunctional acrylates with 3H-5-Thia-1,2,3-triaza-cyclopenta[b]anthracene-10-one (TX-BT) as the one-component photoinitiator was investigated using real-time Fourier transform infrared spectroscopy (RT-FTIR). Photo-differential scanning calorimetric (Photo-DSC) technique was used to study the gelation of trimethylolpropanetriacrylate (TMPTA), P-3038 (epoxydiacrylate (EA) 75% and tripropyleneglycoldiacrylate (TPGDA) 25%) and tripropyleneglycol diacrylate (TPGDA) + P-3038 in the presence of TX-BT. Photopolymerization reactions were performed under different conditions of initiator concentration and UV light intensity.
