1. A curable polymer composition comprising:
(A) a thermoset benzoxazine resin precursor component which does not comprise arylsulphone; (B) an arylsulphone-containing benzoxazine component, and (C) a polyarylsulphone thermoplastic toughening agent component, wherein components (A), (B) and (C) form a single-phase composition, and upon curing, the composition produces a cured resin matrix having a particulate morphology in which component (C) forms discrete particulate phases equal to or less than about 300 μm in size dispersed throughout the cured resin matrix. |
