POLY 83 |
| Low polydispersity poly(tert-butyl acrylate) has been synthesized using atom transfer radical polymerization. The bromine atoms at the end of the polymer chains were replaced by xanthate moieties; the presence of the xanthate groups was confirmed by 1H NMR spectroscopy and the appearance of a peak at 357 nm in the tert-butyl acrylate UV-visible spectrum. Subsequent reversible addition-fragmentation chain transfer polymerization of the altered poly(tert-butyl acrylate) yielded poly(tert-butyl acrylate-block-vinyl acetate). Molecular weight measurements and 1H NMR spectra confirmed block copolymer formation. |
