摘要

Photocuring of new dental resins composed of tri(2-hydroxyethyl) isocyanurate triacrylate (THITA)alone and its mixtures with trimethylolpropane triacrylate (TMPTA) or pentaerythritol triacrylate (PETA)initiated by camphorquinone/amine system was studied by photocalorimetry. Among several different aminesas coinitiators

2-ethyl-4-dimethylaminobenzoate (AM-3)

N-dimethylbenzylamine (AM-5) and 2

6-[tri-(dimethylaminomethyl)] phenol (AM-6) are most effective. Upon irradiation

photopolymerization can occur immediately and no induction period appears in N2 nor in air.Comparing the THITA/TMPTA and THITA/PETA mixtures

the parameters of photopolymerization and hardness of photocured samples show a small difference and only change slightly with varying molar ratios of mixture.In the presence of inorganic filler

the hardness of photocuring resins is almost the same as that for commercial products.
