    摘要： 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.

    摘要： The invention is based on the discovery that adhesive compositions containing certain low-viscosity, mono-ethylenically unsaturated monomers have surprisingly good cure parameters, resulting in very little weight loss upon cure. Many of these monofunctional monomers used alone or in combination with other monofunctional monomers described herein have high glass transition temperatures when cured. Moreover, since these monomers are monofunctional the crosslink density of the adhesive composition does not increase (relative to multi-functional monomers), which in turns results in lower stress, lower modulus adhesive compositions. As such, these monomers are useful in a variety of thermoset adhesive compositions, such as for example, die attach adhesive compositions.

    摘要翻译： 本发明基于以下发现：含有某些低粘度单烯属不饱和单体的粘合剂组合物具有惊人的良好固化参数，导致固化时重量损失非常小。 单独使用或与本文所述的其它单官能单体组合使用的许多这些单官能单体在固化时具有高的玻璃化转变温度。 此外，由于这些单体是单官能的，粘合剂组合物的交联密度不会增加（相对于多官能单体），这又导致较低的应力，较低的模量粘合剂组合物。 因此，这些单体可用于各种热固性粘合剂组合物，例如模具附着粘合剂组合物。

    摘要： The invention generally relates to di-cinnamyl compounds useful in a variety of adhesive applications. More specifically, the invention provides chain-extended bismaleimides and methods for generating them by reaction with di-cinnamyl compounds, including particular di-cinnamyl compounds disclosed herein. Invention di-cinnamyl compounds can also be used as co-monomers in a Diels-Alder type cure, and can act as a co-monomer in a thermoset composition with a maleimide monomer.

    摘要： The present invention provides amorphous maleimide-bismaleimide hybrid mixtures and methods for synthesizing such mixtures by condensation of diamine compounds with maleic anhydride along with one or more additional anhydrides. The invention provides a route to get passed the high melting point and the solubility issues of bismaleimide resins, yet to still obtain the good thermo-mechanical properties of these valuable molecules.

    摘要： 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.
