Effects of nanoparticles on photopolymerization of acrylate monomers in forming nano-composites was written by Check, Casey;Chartoff, Richard;Chang, Sean. And the article was included in European Polymer Journal in 2015.Reference of 4074-88-8 This article mentions the following:
The UV photopolymerization of diethylene glycol-diacrylate and isobornyl-acrylate based nano-composites was studied with respect to reaction conversion with variations in UV light exposure. The composites contained various amounts of well dispersed ZrO2 nanoparticles. The degree of conversion achieved vs light intensity was measured by DSC for various compositions ranging from 0 to 30% by weight of nanoparticles. It was found that including nanoparticles in the monomer increased the conversion achieved considerably. This is attributed to the acceleration of the reaction through interactions with the silane surface ligand on the nanoparticles. The upper limit for conversion was limited because of vitrification and was different for each monomer. Also noted was that the detailed effects of particle concentration on conversion are quite different for the two monomers. Conversion vs. UV exposure data such as those presented provide information necessary for determining the appropriate UV exposure required for creating nano-composites by inkjet printing with optimized phys., mech., and optical properties. The results indicate that it is important to determine this information for forming nano-composites from any specific monomer/nanoparticle combination. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Reference of 4074-88-8).
Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Reference of 4074-88-8
