| titleOfInvention | Tri-functionality photoinitiator and preparation method thereof |
| abstract | The invention relates to a trifunctional photoinitiator and a preparation method thereof, wherein the molecular formula of the trifunctional photoinitiator is C 43 H 44 O 13 And the molecular weight is 769.82. The preparation method is that 2-hydroxy-2-methyl-phenyl acetone (Darocur1173 or HMPP) and chlorinated trimellitic anhydride are used as raw materials, esterification reaction is carried out on the Darocur1173 and the chlorinated trimellitic anhydride, thus acid anhydride is introduced, and then the acid anhydride and 2 molecular photoinitiators [4- (2-hydroxyethoxy) phenyl ] are used for the acid anhydride]-2-methyl-1-propanone (Darocur 2959 or HHMP) to give a trifunctional photoinitiator HTH containing 1 molecule of Darocur1173 and 2 molecules of Darocur 2959 groups. The photoinitiator contains three active groups, so that the molecular weight is increased, the activity is enhanced, and the photoinitiator has excellent mobility, volatility and thermal stability. |
