Applicability of quinolizino-coumarins for monitoring free radical photopolymerization by fluorescence spectroscopy was written by Kaminska, Iwona;Ortyl, Joanna;Popielarz, Roman. And the article was included in Polymer Testing in 2015.SDS of cas: 4074-88-8 This article mentions the following:
Applicability of com. available 2,3,5,6-1H,4H-tetrahydro-quinolizino[9,9a,1-gh]coumarin (Coumarin 6H) and its 9-Me (Coumarin 102), 9-trifluoromethyl (Coumarin 153) and 10-carboxy (Coumarin 343) derivatives as fluorescent mol. probes for monitoring progress of free radical photopolymerization of several acrylic and methacrylic monomers by fluorescence probe technique (FPT) had been tested. The progress of the photopolymerization was monitored using a specially designed cure monitoring system. It was found that all the quinolizino-coumarins shifted their fluorescence spectra towards shorter wavelengths with progress of polymerization, which enabled monitoring the progress in terms of fluorescence intensity ratios as the progress indicator. Coumarin 6H turned out to be the most sensitive to changes occurring during polymerization Coumarin 102 and Coumarin 153 exhibited only about 20% lower sensitivity than that of Coumarin 6H, so those were also good enough for the cure monitoring of acrylic monomers, except for tetraethylene glycol diacrylate, where the quinolizino-coumarins response was disturbed by some fluorescent side product. Moreover, it had been found that the FPT technique has some limitations in the case of monofunctional monomers. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8SDS of cas: 4074-88-8).
Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.SDS of cas: 4074-88-8
