Abstract
Non-isocyanate polyurethane (NIPU) is a sustainable polymer derived from cyclic carbonates and amines. Existing NIPUs are either soluble in polar solvents or insoluble due to cross-linking. This study presents semicrystalline NIPU-acrylate hybrid polymers synthesized via aza-Michael functionalization using biobased acrylates. Acylation with acetic anhydride enhances solubility. These NIPUs combine ester and urethane groups in the backbone and long alkyl ester side chains, offering oil-solubility and semicrystallinity. They serve as wax crystal modifiers or pour point depressants by reducing pour points by up to 21 °C and viscosity by 99%, transforming wax into a flowable spherulitic structure for improved flow assurance.
期刊介绍:
ACS Applied Polymer Materials is an interdisciplinary journal publishing original research covering all aspects of engineering, chemistry, physics, and biology relevant to applications of polymers.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates fundamental knowledge in the areas of materials, engineering, physics, bioscience, polymer science and chemistry into important polymer applications. The journal is specifically interested in work that addresses relationships among structure, processing, morphology, chemistry, properties, and function as well as work that provide insights into mechanisms critical to the performance of the polymer for applications.
