Abstract

Bromoacetylated α-hydroxy-ω methoxy-poly (ethyleneglycol) (M n = 2000 g mol −1 ) was allowed to react with a poly(∊ caprolactone) (M n = 53,700, M w /M n =(1.50) that was first activatedby removing some of the proton atoms borne by the carbon atoms locatedin -position of carbonyl groups using lithium N-N-diisopropylamide as basic reagent in tetrahydrofurane at 78°C under argon flow. The reaction resulted in the grafting of methoxy poly(ethylene glycol) segments to some of the poly("-caprolactone) chains. The resulting polymeric compounds were characterized by various analytical techniques including NMR, SEC, DSC, X-ray diffraction and contact angle. Various characteristics of the recovered compounds, namely degree of substitution, degree of crystallinity, glass transition and melting temperatures, hydrophilicity, were evaluated. It was concluded that grafting was effective but sometimes not all poly("-caprolactone) chains were modified, depending on experimental conditions. Moreover, 150 nm nanoparticles were obtained without any additional surfactant for a 0.74% substitution degree copolymer.

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.
