Also, it is saved from drooling even in the case of light filling with an inorganic compound and it is saved from bubble entrapment and nonuniformity at the time of application with heavy filling. It further exhibits good moldability due to its thixotropic properties. Moreover, it exhibits improved adhesion to polyolefin resins without impairing the past properties. Finally, it gives rise to a cured product which is not excessively hard, with a low elastic modulus, despite filling with an inorganic compound. The composition of the present invention includes components (A) to (B) listed below and is characterized by being fluid at 25° C.

  • Patent number: 9278909
    Abstract: The invention is based on the discovery that a remarkable improvement in the performance of maleimide thermosets can be achieved by incorporating amide-extended maleimides into an adhesive formulation. Amide-extended maleimides described herein can be used to toughen bismaleimide thermosetting materials without sacrificing any thermal stability. Amide-extended maleimides are readily prepared by reacting a bismaleimide with an appropriate amine via the well-known Michael addition reaction. Acylation of the resulting secondary amines provides the amide-extended maleimide. The acylating agent can also be used to introduce polymerizable functional groups into the backbones of these thermoset monomers. Amide-extended acrylate and methacrylate monomers can also be prepared.

  • Publication number: 20140128495
    Abstract: A method for the preparation of an organic-inorganic hybrid composition is performed through three major steps. In addition, a product is generated from this organic-inorganic hybrid composition. In step one, a series of hydrolysis reactions and condensation reactions with a functional organosilane or a combination of functional organosilanes, in presence of water as a reactant for hydrolysis and a suitable acid or a base as a catalyst is performed in order to obtain the first intermediate. In step two, a hydroxyl group-capping intermediate is prepared via reacting a hydroxyl reactable chemical with a hydroxyl functional polymerizable compound. In the third step, a hydroxyl group-capping reaction is conducted with the first intermediate and the hydroxyl group-capping intermediate, so as to obtain the organic-inorganic hybrid composition. It may further include a polymerization step to form an organic-inorganic hybrid polymer composition by UV irradiation or other approaches.
