The monofunctional benzoxazine compounds may be combined with one or more multifunctional benzoxazine compounds to form a unique benzoxazine blend. This benzoxazine blend may be combined with additional components such as catalysts and toughening agents to form a curable resin composition suitable for forming resinous films or composite materials. The presence of monofunctional benzoxazine improves the processability of the benzoxazine-based resin composition by reducing the viscosity of the resin composition, and results in improved tack and drape in the films and composite materials formed from the composition without the loss of modulus in the cured resin.

  • Patent number: 8487068
    Abstract: The present invention provides a method for producing a polybenzoxazole precursor having reduced contents of residual aprotic polar solvent and residual halogen without discharging a large amount of waste water during purification. The present invention specifically relates to a method for producing a polybenzoxazole precursor, which comprises synthesizing a polybenzoxazole precursor in an aprotic polar solvent, adding and mixing water and a water-insoluble solvent with the resulting polybenzoxazole precursor solution to still stand the solution, and then separating a water layer from the solution to reduce a content of impurities remaining in the polybenzoxazole precursor.
