Photopolymerization of ethylenically unsaturated compounds through the use of novel azole photoinitiators
Abstract
Abstract A PROCESS FOR PHOTOPOLYMERIZATION OF ETHYLENICALLY UNSATUREATED ORGANIC COMPOUNDS IS DESCRIBED WHICH COMPRISES IRRADIATING A COMPOSITION INCLUDING A PHOTOPOLYMERIZABLE ETHYLENICALLY UNSATURATED ORGANIC COMPOUND AND AS A PHOTOPOLYMERIZATION INITIATOR AN AZOLE COMPOUND HAVING THE FORMULA: R3-C<(-X-C(-R2)=C(-R1)-N=) WHEREIN: X IS OXYGEN, SULPHUR,-NH-OR A-NR-GROUP, WHEREIN R IS AN ALKYL GROUP OF 1 TO 4 CARBON ATOMS, OR BENZYL, EACH OF R1 AND R2 (SAME OR DIFFERENT) IS HYDROGEN, HALOGEN, AN ALKYL GROUP OF 1 TO 4 CARBON ATOMS, OR A PHENYL GROUP, AND R3 IS HYDROGEN, HALOGEN, AN ALKYL GROUP OF 1 TO 4 CARBON ATOMS, A PHENYL GROUP, A NAPHTHYL GROUP OR A STYRYL GROUP; OR AN AZOLE COMPOUND WHICH COMPRISES AN IMIDAZOLE GROUP INCORPORATED IN A POLYMER COMPRISING RECURRING UNITS OF THE FORMULA: -(CH2-CH(-IMIDAZOL-4-YL)
