Copolymer Synthesis of N‐Vinylacetamide and 2‐Methylene‐1,3‐Dioxepane Provides a New Degradable Polymer

Journal of Polymer Science, Volume 63, Issue 6, Page 1306-1318, 15 March 2025.
ABSTRACT N‐vinylamides, especially noncyclic N‐vinylacetamide (NVA), have been used in various applications such as biomaterials, surfactants, and hydrogels. However, their potential to copolymerize with cyclic ketene acetal (CKA) to create degradable polymers is underexplored.
