5‐Hydroxymethylfurfural Derivative Based Thermoplastic Elastomers Synthesized via Thiol‐Michael Addition Reaction Utilizing Poly(lactic acid) as Hard End Blocks
Bibliographic record
Abstract
Abstract 5‐Hydroxymethylfurfural derivative based thermoplastic elastomers (TPEs) are efficiently synthesized via a two‐step thiol‐Michael addition reaction using polylactide (PLA) as the hard segments in a one‐pot reaction under mild conditions. The first step involves the synthesis of prepolymers having thiol groups as end groups. The macromolecular coupling reaction which occurs between the prepolymers and the PLA having acrylate‐end groups is demonstrated via 1 H NMR and gel permeation chromatography (GPC). Additionally, by varying the ratio of 1,3‐propanedithiol and 2,5‐furan diacrylate, TPEs with soft segments having different molecular weights are synthesized, and then characterized. The cyclic tensile tests demonstrate the elasticity of the synthesized TPEs. Furthermore, the Diels–Alder reaction is used to dynamically crosslink the soft segments in the TPEs, leading to the increased mechanical properties in terms of Young's modulus and tensile strength.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
