Arget atrp of methyl methacrylate in the presence of nitrogen-based ligands as reducing agents

Kwak, Yungwan, Matyjaszewski, Krzysztof·2009·Polymer International

Abstract

BACKGROUND: Activators regenerated by electron transfer for atom transfer radical polymerization (ARGET ATRP) employs reducing agents (e.g. ascorbic acid, tin(II) 2‐ethylhexanoate) to continuously reduce a deactivator Cu(II) to an activator Cu(I) species. In this work, copper‐mediated ARGET ATRP of methyl methacrylate (MMA) was studied in the presence of excess aliphatic nitrogen‐based ligands that served not only as ligands but also as reducing agents. RESULTS: Reduction of Cu(II) to Cu(I) by an excess amount of nitrogen‐based ligand was followed by UV‐visible spectroscopy. Well‐controlled poly(methyl methacrylate) (PMMA) with low polydispersity index (PDI) was prepared in the presence of Cu(II)Br 2/excess ligand via ARGET ATRP. Chain extension of PMMA with MMA was successful, resulting in low‐PDI PMMA and demonstrating well‐maintained end‐group functionality. CONCLUSION: Well‐controlled PMMA with low PDI was prepared via ARGET ATRP in the presence of Cu(II) and nitrogen‐based ligands without any additional reducing agent. Aliphatic nitrogen‐based ligands for ATRP can serve as reducing agents as well as ligands. Copyright © 2009 Society of Chemical Industry

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.
