Multishape memory effect of norbornene-based copolymers with cholic acid pendant groups

Shao, Yu, Lavigueur, Christine, Zhu, X. X.·2012·Macromolecules

Abstract

Multishape memory copolymers were prepared through copolymerization of two norbornene derivatives: one based on cholic acid and the other on triethylene glycol monomethyl ether. The glass transition temperature ( T g ) of the copolymers can be tuned over a temperature range from −58 to 176 °C. Most of these copolymers displayed a very broad T g over a 20 °C range which can allow a multishape memory effect. The shape memory properties of the copolymer incorporating an equal molar amount of both monomers have been studied in detail. The multishape memory effect was investigated by dynamic mechanical analysis using a thermomechanical programming process, in which multiple steps created two, three, and four temporary shapes. The polymer displayed good shape fixing and recovery in different thermal processing stages over the broad glass transition range. This series of copolymers with broad and tunable T g ’s may be useful as functional materials with multishape memory effect.

Recomputing p-values needs the paper’s full text.

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?

  • The temperature-memory effect approach has been largely employed to achieve multiple-way SMPs with a broad glass transition or a broad melting transition as the switching transition.

    “Such an approach has been largely employed to achieve multiple-way SMPs with a broad glass transition [82-92] and a broad melting transition [93-95] as the switching transition.”

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.
