Synthesis of Star Polymers by a Combination of ATRP and the “Click” Coupling Method
Abstract
Three-arm and four-arm star polystyrene (PS) polymers were synthesized by a combination of atom transfer radical polymerization (ATRP) and click coupling chemistry. The click reaction between an azido-terminated PS (PS−N 3 ) and an alkyne-containing multifunctional compound proved to be fast and efficient. All coupling reactions were finished within 3 h, proven by the disappearance of signals from the azido groups in NMR spectra and the high yields of the coupled products by GPC analysis. For the model coupling reaction between a PS−N 3 polymer and a dialkyne-containing compound, the final yield of the coupled PS−PS polymer was ca. 95%. When a PS−N 3 polymer was reacted with a trialkyne-containing or tetraalkyne-containing compound, the yields of 3-arm star and 4-arm star polymers were around 90% and 83%, respectively. The influence of several parameters on the efficiency of the click coupling reaction was studied, including the molecular weight of the PS−N 3 polymer, the presence of an added reducing agent, Cu(0), and the stoichiometry between the azido and alkynyl groups. The results indicated that the yield of the coupled product was higher when a lower molecular weight PS−N 3 was employed in conjunction with a small amount of reducing agent, and the molar ratio of azido and alkynyl groups was close to 1.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
