AI Article Synopsis
- The study explores the synthesis of polymer coatings using renewable resources, seeking to merge the benefits of water-borne and solvent-borne coatings.
- After polymerization, a renewable compound, 4-oxocyclopentenyl acrylate (4CPA), is capable of forming cross-linked structures when exposed to UV light, leading to impressive physical properties in the final products.
- The research finds that the resulting latexes from the polymerization process are stable, environmentally friendly, and can create flexible to rigid films, making them suitable for use as barriers in paper coatings.
Article Abstract
After the development of polymer coatings and films based on renewable resources, there remains a challenge of combining the advantages of water-borne acrylic latexes with the excellent physical properties of cross-linked solvent-borne coatings. After polymerization, the renewable 4-oxocyclopentenyl acrylate (4CPA) is capable of undergoing photocyclodimerization under UV light, yielding a cross-linked polyacrylate. In this work, we investigate the polymerization-induced self-assembly (PISA) of 4CPA with several renewable acrylic monomers in the presence of a macro-RAFT agent. The produced latexes have a small particle size, good colloidal stability, and are free of volatile organic compounds. After film formation and UV curing, flexible to rigid films can be obtained depending on the monomer composition and UV irradiation time. The cross-linked films show promise as oil and water barriers in paper coating applications. This work outlines the development and application of renewable and functional cross-linkable latexes synthesized by PISA.
