Developing non-isocyanate urethane-methacrylate photo-monomers for 3D printing application.

ABSTRACT: Urethane-methacrylate photo-monomers were prepared via a non-isocyanate route for the 3D printing application. The monomers were synthesized through reacting aliphatic amines, i.e. 1,6-hexanediamine, 1,4-butanediol bis(3-aminopropyl) ether, or n-butylamine, with cyclic carbonates, i.e. ethylene carbonate or propylene carbonate, followed by the methacrylation of the generated hydroxylurethanes. The effects of the chemical structure of monomers on their photo-reactivity and physicomechanical properties of the cured samples were studied. Propylene carbonate generated side methyl groups within the urethane block, which significantly limited the crystallization of the monomers resulting in high photo-reactivity (R _p,max = 6.59 × 10^-2 s
