Biodegradable Polyesteramide Films for Pervaporative Dehydration of Isopropanol–Water
Journal of Applied Polymer Science, Volume 142, Issue 38, October 10 2025.ABSTRACT Polyesteramides are biodegradable polymers possessing good mechanical properties with potential applicability in membrane separations. In this work, polymer films from ε‐caprolactam and ε‐caprolactone‐based polyesteramides were prepared at a ratio of monomer units set so that the resulting copolymer had a low crystalline phase content.
