Abstract

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-OCH2COOH), 2-
Thioxanthone-Thioacetic Acid (TX-SCH2COOH) and 2-Mercaptothioxanthone
(TX-SH). Photopolymerization reactions were performed under identical
conditions of temperature, initiator concentration and UV light intensity and in
this chapter the effect of light intensity and concentration of initiator was also
reported for photoinitiator 2-Mercaptothioxanthone (TX-SH).
