Abstract

Atom transfer radical polymerization (ATRP) with concurrent reverse and normal initiation process was investigated. Bulk polymerizations of both n -butyl acrylate (BA) and styrene (St) were conducted using CuBr 2 complexed with 1 equiv of tris(2-(dimethylamino)ethyl)amine (Me 6 -TREN) as the catalytic system, initiated by 2,2‘-azobis(isobutyronitrile) (AIBN) and an alkyl halide (RX). Polymerization of BA at 60 or 90 °C provided well-defined polymers with molecular weights up to 40 000 g/mol and low polydispersities ( M w / M n < 1.10). Similar results were obtained for the polymerization of styrene at 110 °C. The effects of polymerization temperature and solubility were studied in order to moderate the high activity of the catalyst and the poor solubility of the Cu(II) complex in monomers. Additionally, other parameters influencing this ATRP process are discussed.

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.
