Morinaga, Hisatoyo; Sawatani, Takeru published the artcile< Metal- and halogen-free one-pot synthesis of functional oligomers by tetra-n-butylammonium acetate/alcohol system>, Quality Control of 112-63-0, the main research area is tertiary butylammonium acetate initiator glycidyl phenyl ether oligomer.
In this study, ring-opening polymerization of glycidyl Ph ether (GPE) is performed using tetra-n-butylammonium acetate (n-Bu4NOAc) as a metal- and halogen-free initiator. Various alcs. are used as chain transfer agents (CTAs), of which ethanol yields oligo-GPE with a controlled number-average mol. weight (Mn) of relatively narrow polydispersity (Mw/Mn = 1.27-1.33). This polymerization system facilely affords various functional oligomers, including amphiphilic block copolymer, reactive oligomer, and branched oligomer from poly(ethylene glycol) Me ether, allyl alc., and polyhydric alc. as the resp. CTAs. The terminal chain structures are confirmed via NMR and MALDI-TOF MS anal.
Polymer Bulletin (Heidelberg, Germany) published new progress about Chain transfer agents. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Quality Control of 112-63-0.
