Preparation and Properties of Poly(urethane-benzoxazine)s Based on Monofunctional Benzoxazine Monomer [PDF]
Polymer Journal, 2001 Poly(urethane-benzoxazine) films were prepared by blending a monofunctional benzoxazine monomer, 3-phenyl-3,4-dihydro-2H-1,3-benzoxazine (Pa), and polyurethane (PU) prepolymer that was synthesized from 2,4-tolylene diisocyanate and polyethylene adipate polyol (Mw ca. 1000) in 2:1 molar ratio, followed by casting as films and thermal curing of the films.
