So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Decker, Christian; Morel, Florence; Jonsson, Sonny; Clark, Shan; Hoyle, Charles researched the compound: 1-(tert-Butyl)-1H-pyrrole-2,5-dione( cas:4144-22-3 ).Recommanded Product: 4144-22-3.They published the article 《Light-induced polymerization of photoinitiator-free vinyl ether/maleimide systems》 about this compound( cas:4144-22-3 ) in Macromolecular Chemistry and Physics. Keywords: radical photopolymerization kinetics vinyl ether maleimide photoinitiator free. We’ll tell you more about this compound (cas:4144-22-3).
The photo-induced copolymerization of electron donor/electron acceptor monomers was studied by real-time IR spectroscopy. With stoichiometric maleimide-vinyl ether mixtures, the reaction was found to proceed within seconds upon UV exposure. For systems with an excess of vinyl ether, the 2 monomers disappeared at essentially the same rate, to generate an alternating copolymer. In such photoinitiator-free systems, the initiating radicals are mainly formed by H abstraction by the excited maleimide mols. Highly crosslinked polymer networks were obtained by light-induced copolymerization of bismaleimide and divinyl ether monomers. One of the distinct characteristics of this type of radical-induced polymerization, beside the absence of any added photoinitiator, is that it is less sensitive to O inhibition than the conventional UV-curable acrylate resins.
