Critical phenomenon during photoinitiated gelation at different temperatures: A Photo-DSC study

Photo-DSC Investigation of Acetonaphthone Type Photoinitiators at Different Light Intensities

“…It is of high possibility that high light intensity leads to a high cross-section for initiation, which results in production of more formed primary radicals on the surface of the solution. These excess radicals formed on the surface of the coating restricted the penetration of UV light into the samples by creating a filter effect, which resulted in a decrease of the final conversion values at high light intensities [1,15,16]. As can be seen in Figs.…”

“…The effect of light intensity and exposure time on photopolymerization has been also explored by different scholars. Accordingly, UV light intensity was identified among the most important factors which affect the reaction kinetics of resin systems and properties of formed gels [15,16].…”

Difluoroboranyl derivatives as efficient panchromatic photoinitiators in radical polymerization reactions

“…Photoinitiated radical polymerization, which is one of the most common and useful polymerization reactions, may be initiated by one-component system leading to homolytic cleavage process (type I PI) or by two-component systems producing radicals through a hydrogen transfer, an electron/proton transfer or an energy transfer (type II PI). The type II PIs are generally composed of PI and either a hydrogen donor (HD) or a photosensitizer (PS) [18][19][20][21][22]. One-and two-component systems are also used to start photoinduced cationic polymerization.…”
