The epoxy-based oligosiloxanes were synthesized from the reaction of 3-glycidoxypropyltrimethoxysilane, diphenylsilanediol (DPSD). Previously known cross-linking agent such as a methyl hexa-hydrophthalic anhydride (MHHPA) for the synthesis of epoxy-based polysiloxane resins in the present of amine catalyst showed disadvantage in terms of long curing time. To obtain suitable hardness for polysiloxane resins, the curing time to complete the reaction requires 12 hours. Here, we reported new aromatic anhydrides as a ultra-fast curing agent for the synthesis of epoxy-based polysiloxane resins. The curing process with non-aromatic anhydride requires usually more than 12 hours. However the curing process with aromatic anhydrides requires only about 30 min to obtain a suitable hardness. Prepared epoxy-based polysiloxane resins exhibited an ultra-fast curing time, good refractive index, and high hardness and transmittance. This research was financially supported by the Ministry of Education (MOE) and National Research Foundation of Korea(NRF) through the Human Resource Training Project for Regional Innovation (No. 2012H1B8A2026282)
