| Abstract: | hoto-initiation behavior of N-(4-benzoylphenyl)maleindde (NBPMI),combining with dimethyaminoethyl metharylate (DMAEMA) or its polymer P(DMAEMA) was studied. The photopolymerization rate equations and their overall activation energies were obtained as follows:Rp∝NBPMI]0.48DMAEMA]0.18 MMA]0.82 Ea=26.8 kJ /mol Rp∝P(NBPMI-DMAEMA)]0.32MMA]0.92 Ea=21.7 kJ /mol Rp∝NBPMI]0.38 P(DMAEMA)]0.65MMA]0.70 Ea=33.2 kJ /mol The polymeric photoinitiator system shows higher initiation ability than that of the monomeric one. The UV spectrum of P(MMA) initiated by the NBPMI-DMAEMA system indicate that both NBPMI and DMAEMA not only initiate the polymerization of MMA, but also enter into P(MMA) polymer chains. |
