Relationship between the hetarylamine chemical structure, crystal packing in homo- and co-crystals, and fluorescence effects (quenching, bathochromic and hypsochromic shifts).
The role of the alkyl fragment of alkoxyamine initiating the homopolymerization of styrene is experimentally and theoretically studied in the case of 2,2,6,6 tetramethylpiperidine 1 oxyl derivatives. The rate constants of homolysis and recombination are measured for the alkoxyamines under study. The charac teristics of polymerization initiated by these compounds are experimentally examined. The kinetics of poly merization is theoretically calculated with allowance for the measured kinetic parameters and the experimen tally detected side reaction of hydrogen atom transfer to the nitroxide radical during the thermolysis of alkoxyamine 2 cyano 2 isopropyl-TEMPO.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
