Abstract

This work reports the first successful synthesis of polycaprolactone (PCL)-based degradable ionomers using free-radical chemistry. Degradable cationic ionomers were synthesized by random radical terpolymerization of 2-methylene-1,3-dioxepane (MDO), methyl methacrylate (MMA), and N,N -dimethylaminoethyl methacrylate (DMAEMA) and followed by quaternization of amine with alkyl bromide. The terpolymerization of MDO, MMA, and DMAEMA led to a polymer with ester group randomly distributed in the polymer chains. The small-angle X-ray scattering (SAXS) analysis, the transmission electron microscope (TEM), and dynamic mechanical analysis (DMA) showed ionic aggregates existing in ionomers. Ionomers quaternized by ethyl bromide showed relative strong ionic interaction and showed aggregates with a diameter around 30 nm, which had a separate glass transition temperature ( T g ) and performed rather as filler material. Ionomers containing 40 mol % of ester group and 20 mol % of ionic group showed biodegradability after being buried in compost.

  • Increasing interest in biodegradable polyesters and the versatility of RROP with respect to structures accessible via different monomers and their copolymerization with conventional vinyl monomers has changed the situation significantly.

    “However, with the increasing interest in biodegradable polyesters and the versatility of RROP with respect to the structures accessible via very different monomers [25] and their copolymerization with conventional vinyl monomers [26 -34] has changed the situation significantly.”

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.
