    Abstract: Disclosed herein are monofunctional benzoxazine compounds having at least one electron-withdrawing group. 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.

    Abstract translation: 本文公开了具有至少一个吸电子基团的单官能苯并恶嗪化合物。 单官能苯并恶嗪化合物可以与一种或多种多官能苯并恶嗪化合物组合以形成独特的苯并恶嗪混合物。 该苯并恶嗪共混物可以与另外的组分如催化剂和增韧剂组合以形成适于形成树脂膜或复合材料的可固化树脂组合物。 单官能苯并恶嗪的存在通过降低树脂组合物的粘度来提高苯并恶嗪类树脂组合物的加工性，并且导致由组合物形成的膜和复合材料中的粘性和悬垂性改善，而固化树脂的模量不损失 。

    Abstract: A structural adhesive composition that is suitable for high-strength bonding of metals and aerospace structural materials. In one embodiment, the structural adhesive composition based on a two-part system, which is curable at or below 200° F. (93° C.). The two-part system is composed of a resinous part (A) and a catalyst part (B), which may be stored separately at room temperature until they are ready to be used. The resinous part (A) includes at least two different multifunctional epoxy resins with different functionality selected from difunctional, trifunctional, and tetrafunctional epoxy resins, certain toughening components, and inorganic filler particles as a rheology/thixotrophy modifying component. The toughening components include core-shell rubber particles with different particle sizes and at least one of an elastomeric polymer and a polyethersulfone polymer. The catalyst part (B) includes an aliphatic or cyclic amine compound as a curing agent and inorganic filler as a rheology/thixotropy modifying component. The weight ratio of part (A) to part (B) is within the range of 3:2 to 10:2. In another embodiment, the structural adhesive composition is based on a one-part system which includes the components of the resinous part (A) in the two-part system mixed with a latent amine curing agent. The one-part system may further include an imidazole and/or an aliphatic amine. The one-part system is curable within the temperature range of 140-300° F. (60-150° C.). The paste adhesive disclosed herein has film-like properties and is particularly useful in rapid-assembly aerospace structure bonding applications.
