Pentaerythritol and Glycerol Ester-Based Rosin-Modified Hydroxyl-Terminated Polybutadiene (HTPB).
Article in ACS polymers Au, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Hydroxyl-terminated polybutadiene (HTPB) has widespread applications such as in adhesives, coatings, and solid propellants due to its durability and excellent mechanical strength when cross-linked, which can be maintained at low temperatures. However, many of the additives used to modify the properties of HTPB are not sustainably sourced nor have the functionality such that tailoring of HTPB properties can be achieved. Here, we describe the use of the pentaerythritol ester of rosin (PER) and glycerol ester of rosin (GER), sourced from gum rosin (pine trees), to modify the rheology and mechanical properties of uncross-linked and cross-linked HTPB. Both rosin esters are compatible with HTPB resulting in a change in the glass transition temperature (
