Paper Abstract

On the basis of the chemical structure of (5-Hydroxyimino-5H-thiophen-2-ylidene)-phenylacetonitrile, we synthesized a novel sulfonic oxime ester photoacid generator named (5-Ptoluenesulfonyloxyimino- 5H-thiophen-2-ylidene)-phenyl-acetonitrile (TTPA),which was an efficient Photoacid generator (PAG) for 405nm violet laser imaging system.It was synthesized from 2- Nitrothiophen ,Phenylqceto-nitrile and P-toluenesulfonyl chloride.TTPA was characterized by FTIR1HNMR and UV absorption spectra. Real time infrared spectroscopy(RTIR) was used to investigate the effect of different monomers system and different concentrations of TTPA on the polymerization kinetics. The results showed that with the concentration of TTPA increase, with limits, the rate of photopolymerization(Rp) and final double bond conversion increased and the induction period shortened.
