摘要:
The invention is directed to maleimide thermosets incorporating imide-extended mono-, bis-, or polymaleimide compounds. These imide-extended maleimide compounds are prepared by the condensation of appropriate anhydrides with appropriate diamines to give amine terminated compounds. These compounds are then condensed with excess maleic anhydride to yield imide-extended maleimide compounds.

The invention is based on the discovery that certain well-defined functionalized cyclic siloxanes are useful as thermosetting resins for the electronic packaging industry. The functionalized cyclic siloxane compounds described herein can be cured in a variety of ways, depending on the polymerizable moiety incorporated into the compound. Invention cyclic siloxanes are readily prepared via hydrosilation of polyalkyl(hydro)cyclosiloxanes with appropriately functionalized alkenes and/or alkynes.

In accordance with the present invention, there are provided novel benzoxazine compounds and thermosetting resin compositions prepared therefrom. Invention compositions are particularly useful for increasing adhesion at interfaces within microelectronic packages. Invention benzoxazines are useful for the preparation of invention compositions with properties which are associated with increased adhesion at interfaces, such as, for example, low shrinkage on cure and low coefficient of thermal expansion (CTE). In another aspect of the invention, there are provided die-attach pastes having increased interfacial adhesion. Invention die-attach pastes include benzoxazine-containing thermosetting resin compositions. In further aspects of the invention, there are provided methods for enhancing adhesive strength of thermosetting resin compositions and methods for enhancing adhesion of a substrate bound to a metallic surface by a thermosetting resin composition.

Low viscosity, radiation curable compositions have been developed that produce plastics with silicone rubber-like properties. These compositions have also been shown to give great adhesion to plastics. The combination of an ethylenically unsaturated oligomer with di- or polythiol compound, reactive diluents and a radical initiator will produce these properties. These materials can find use in many areas such as: Electronics packaging, displays, conformal coatings, seals, gaskets, fiber optics coatings, and golf ball coatings.

The invention provides hetero-functional compound compounds useful in a variety of adhesive applications. More particularly, the invention provides compounds bearing at least one electron rich olefinic bond and at least one electron poor olefinic bond, wherein the two olefinic bonds are separated by a C3 to about C500 aliphatic, cycloaliphatic, or aromatic spacer.

The invention is based on the discovery that a remarkable improvement in the performance of maleimide thermosets can be achieved through the incorporation of imide-extended mono-, bis-, or polymaleimide compounds. These imide-extended maleimide compounds are readily prepared by the condensation of appropriate anhydrides with appropriate diamines to give amine terminated compounds. These compounds are then condensed with excess maleic anhydride to yield imide-extended maleimide compounds.
