Abstract

The vast differences in material properties accessible via crosslinking of sidechain-functionalized polymers are driven by topology.

  • Topological defects including intra-chain cycles, dangling chains, and free chains affect macroscopic mechanical and thermomechanical properties of real polymer networks in a non-constructive way but are statistically unavoidable.

    “These defects affect the macroscopic mechanical and thermomechanical properties in a non-constructive way, but are statistically unavoidable30,31.”

    From On demand shape memory polymer via light regulated topological defects in a dynamic covalent network (2020) · cites this paper as [31]

    The rheology passage (section labeled Abstract; page unavailable) reports that primary and higher-order loops affect shear storage modulus, and that statistically distributed functional groups can produce strands too short to be elastically effective. It does not establish that dangling and free chains have the claimed effects, address thermomechanical properties, or say that all the listed defects are statistically unavoidable. (LLM, conf=0.84)

  • The presence of loops that consume functionality yet do not contribute to gelation will further lower the number of degradable bonds needed to achieve degradation.

    “the presence of loops that consume functionality yet do not contribute to gelation will further lower the number of degradable bonds needed to achieve degradation (vide infra). 26”

    From Cleavable comonomers enable degradable, recyclable thermoset plastics (2020) · cites this paper as [26]

    The discussion of gelation (page unavailable) reports that materials with loop fractions above approximately 0.7 were soluble, supporting the point that loops can consume reacted functionality without building a gel-spanning network. The paper uses cleavable groups to measure loops, but it does not establish that loops lower the number of degradable bonds needed to degrade a network. (LLM, conf=0.86)

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.
