Summary: In recent years, the search for environmentally friendly monomers has gradually increased as an important field, attracting the attention of researchers worldwide. Our approach to obtaining lactic acid-based polymers entails the use of an environmentally friendly monomer, derived from lactic acid (ELA), presenting double-bond functionality, allowing it to undergo free-radical polymerization, while further having an eco-friendly water-based miniemulsion polymerization process. It has been demonstrated that the ELA/methyl methacrylate (MMA) copolymer can successfully be synthesized. Highly stable latexes were obtained at high conversion. The incorporation of ELA and its effect on the copolymer properties were evaluated; results indicated that polymer properties such as average molar masses and glass transition temperatures are strongly dependent on the ELA composition.
