Publisher and Date:(Taylor & Francis Inc, 2009)A photo-differential scanning calorimetric (Photo-DSC) technique was used to study the photoinitiated radical polymerization of a 75% epoxy diacrylate (EA) and 25% tripropyleneglycoldiacrylate (TPGDA) mixture with 2-mercaptothioxanthone (TX-SH) as photoinitiator by using different light intensities. Photopolymerization reactions were carried out under identical conditions of temperature and initiator concentration. It was observed that all conversion curves during gelation at various Might intensities ...
Investigation of PSt-MWCNT concentration on epoxyacrylate photopolymerization and conductivity of polymer films Authors:Doğruyol, Zekeriya; Temel, Gökhan; Doğruyol, Sevnur Keskin; Pekcan, Önder; Arsu, Nergis
Publisher and Date:(Elsevier Science SA, 2013)Photopolymerization kinetics and conductivity changes of epoxyacrylate composites for various loading modified PSt-MWCNT weight fractions changing from 0.0025 to 0.2 wt.% were evaluated by performing photo differential scanning calorimetry (photo-DSC) and four point conductivity measurements. 0.2% PSt-MWCNT additive polymeric films had their electrical conductivity boosted by 6% more than non-additive polymeric films.

Publisher and Date:(Elsevier Science SA, 2015)The gelation of epoxy acrylate (EA) 80% and tripropyleneglycol diacrylate (TPGDA) 20% was studied through the use of photo-differential scanning calorimetric (photo-DSC) technique in the presence of a thioxanthone based initiator. Photo-induced polymerization reactions were performed under identical conditions of temperature initiator concentration and UV light intensity in various NN-dimethylformamide (DMF) contents. Photo-DSC technique allowed us to monitor the gelation without disturbing the ...
Universality in gelation of epoxy acrylate with various photoinitiators: a photo differential scanning calorimetric study Authors:Doğruyol, Zekeriya; Karasu, Feyza; Balta, Demet Karaca; Arsu, Nergis; Pekcan, Önder
Publisher and Date:(Taylor & Francis Ltd, 2008)Photo-differential scanning calorimetric (Photo-DSC) technique was used to study the gelation of P-3038 (epoxy acrylate (EA) 75% and tripropyleneglycoldiacrylate (TPGDA) 25%) in the presence of various thioxanthone-based initiators namely thioxanthone (TX) 5-thia-naphtacene-12-one (TX-NP) 2-(carboxymethoxy) thioxanthone (TX-OCH(2)COOH) 2-thioxanthone-thioacetic acid (TX-SCH(2)COOH) and 2-mercaptothioxanthone (TX-SH). Photopolymerization reactions were performed under identical conditions of ...
