One‐Step Solvent‐Free Synthesis of Dimer Diamine‐Based Autocatalytic Polyol for the Preparation of Polyurethane Foams

open access: yesMacromolecular Materials and Engineering, Volume 309, Issue 5, May 2024.
A dimer diamine‐based autocatalytic polyol (TETRAOL) is synthesized with 100% atom economy. TETRAOL is synthesized in a one‐pot and one‐step reaction. Bio‐based foams are prepared by using TETRAOL and vegetable oil‐based polyols. Polyurethane foams display good thermal and mechanical properties.
