A non-isocyanate pathway was used to synthesize a urethane methacrylate monomer, 2-((methylcarbamoyl)oxy)ethyl methacrylate (MEM) and methacrylic acid (MAA). The MEM and MAA mixture was copolymerized with MMA and BA in a semicontinuous monomer-starved process to prepare latexes via emulsion polymerization. Varying amounts of MEM and MAA monomers were introduced to the latex, and their effect on the thermal properties, film formation, viscoelastic, mechanical and morphological properties was examined. The upper limit functionality concentration was evaluated based on the latex stability. Incorporation of MEM and MAA in latexes enhanced film formation properties displayed by lowering MFFT. MEM and MAA functionalized latexes exhibited enhanced Young’s modulus, tensile strength and hardness compared to the control latex without any MEM and MAA.
