New Biobased Polyester Polyols With Tunable T
Article in ChemSusChem, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Polyesters (PEs) are among the most important classes of plastics. The identification of new, biobased, and renewable sources is necessary to increase the sustainability of PEs and related materials production. Herein, we describe the synthesis of three epoxy monomers derived from 4-vinylguaiacol, a functional molecule easily obtained from biobased ferulic acid. These monomers, namely 4-epoxyguaiacol acetate, butanoate, and hexanoate, were used in ring-opening copolymerization reactions in combination with different cyclic anhydrides, promoted by simple, (organo)catalytic initiators [i.e., bis-(triphenylphosphine)iminium chloride, tetrabutylammonium bromide, 4-(dimethylamino)pyridine, and cesium acetate]. Reactions were carried out with and without solvents, allowing the synthesis of 12 new and structurally different PEs containing up to 100% renewable monomers. The obtained PEs have number-average molecular weights (M
