From Polyethylene to Polyester: Influence of Ester Groups on the Physical Properties

Pepels, Mark P. F., Hansen, Michael Ryan, Goossens, Han, Duchateau, Rob·2013·Macromolecules

Abstract

Aliphatic long-chain polyesters (ALCPEs) were synthesized using the ring-opening metathesis copolymerization of ambrettolide and cis -cyclooctene followed by exhaustive hydrogenation, yielding saturated ALCPEs with methylene-to-ester ratios (M/E) varying from 15 to 223 and ∞ (polyethylene), of which the ester groups were pseudo randomly distributed over the backbone of the polymer. The melting temperature of these ALCPEs showed an inverse proportional trend with respect to the amount of ester groups in the polymer structure, ranging from 132.1 °C (M/E = ∞) to 91.5 °C (M/E = 15), of which the former is comparable to the melting temperature of high-density polyethylene. The crystallinity and the orthorhombic unit cell of the polymers did not significantly change with increasing M/E. Solid-state NMR was used to show the uniform partitioning of the ester groups over the crystalline and amorphous phase. Even though the lamellar thickness showed a decrease with increasing amount of ester groups, this did only partly explain the decrease in melting temperature. The main factor determining the decrease in melting temperature is the inclusion of ester groups in the crystal lattice, which causes the crystal lattice to be less stable.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Ester functionality does not drastically impact the unit cell identity relative to PE but leads to decreased lamellar thickness, destabilization of the crystal lattice, and lowering of the melting transition temperature (Tm).

  • The crystallites were smaller in size than LLDPE or HDPE samples due to the presence of the ester group.

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.
