摘要:
The invention is based on the discovery that certain crosslinkable functional groups can be incorporated into olefin oligomers, thereby making these functionalized olefin oligomers useful as thermosetting resin compositions. In particular, there are provided olefin oligomers containing pendant maleimide groups. These materials are readily prepared via cationic co-polymerization of cationically polymerizable olefin monomers and maleimide monomers containing a cationically polymerizable functional group.

摘要:
In accordance with the present invention, there are provided novel thermosetting resin compositions which do not require solvent to provide a system having suitable viscosity for convenient handling. Invention compositions have the benefit of undergoing rapid cure. The resulting thermosets are stable to elevated temperatures, are highly flexible, have low moisture uptake and are consequently useful in a variety of applications, e.g., in adhesive applications since they display good adhesion to both the substrate and the device attached thereto.
摘要:
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.
