Plasticization of PVC was carried out by covalently linking phthalate derivatives via copper-free (thermal) or copper catalyzed azide-alkyne cycloadditions. Di(2-ethylhexyl) phthalate derivatives (DEHP-ether and DEHP-ester) were synthesized and appen

Synthesis of fluorinated alkoxyamines and alkoxyamine-initiated nitroxide-mediated precipitation polymerizations of styrene in supercritical carbon dioxide

Autor: Christopher Magee, Fawaz Aldabbagh, Aruna Earla, Rebecca Braslau, Jennifer Petraitis, Chad M. Higa, Per B. Zetterlund

TIPNO (2,2,5-trimethyl-4-phenyl-3-azahexane-3-nitroxide)-alkoxyamine was found to give reasonably controlled/living nitroxide-mediated (NMP) precipitation polymerizations of styrene in supercritical carbon dioxide (scCO(2)). In contrast under the sam

Covalently linked plasticizers: triazole analogues of phthalate plasticizers prepared by mild copper-free 'click' reactions with azide-functionalized PVC

Autor: Aruna Earla, Rebecca Braslau

Publikováno v: Earla, A; & Braslau, R. (2014). Covalently linked plasticizers: triazole analogues of phthalate plasticizers prepared by mild copper-free “click” reactions with azide-functionalized PVC. Macromolecular rapid communications, 35(6), 666-671. doi: 10.1002/marc.201470020. UC Santa Cruz: Retrieved from: http://www.escholarship.org/uc/item/28t8g1xw
Macromolecular Rapid Communications, vol 35, iss 6

Copper-free azide-alkyne click chemistry is utilized to covalently modify polyvinyl chloride (PVC). Phthalate plasticizer mimics di(2-ethylhexyl)-1H- triazole-4,5 dicarboxylate (DEHT), di(n-butyl)-1H-1,2,3-triazole-4,5- dicarboxylate (DBT), and dimet
