    Abstract: An adhesive tape for lead-on-chip (LOC) IC applications containing a polyamide-based adhesive composition which is the reaction product from a reaction mixture of: (a) a pre-imidized polyamic acid; and (b) a bismaleimide that has been modified by a barbituric acid of a derivative of barbituric acid to become a barbituric acid modified bismaleimide. The pre-imidized polyamic acid is a reaction product from a reaction mixture that contains a polyamic acid and a cyclizing agent. The polyamide-based adhesive composition provides all the desirable heat resistance and other mechanical and dielectric characteristics. But, most significantly, its microscopic rheological properties are adjusted such that excellent contact is achieved between the resin molecules and the lead frame surface while eliminating or at least minimizing the extent of adhesive overflow, which can substantially reduce the reliability of the final IC product.

    Abstract: A heat resistant composition comprising a mixture of (a) a polyurethane or a modified polyurethane and (b) a bismaleimide oligomer, in which the bismaleimide oligomer is in an amount of about 1 to 35 percent by weight based on overall solid contents. The polyurethane is formed by reacting a diisocyanate-containing compound with a dihydroxy diol-compound. Then the polyurethane is reacted with a trimellitic anhydride, a diacid or a mixture thereof to form the modified polyurethane. The bismaleimide oligomer is formed by reacting a bismaleimide resin with a barbituric acid or a derivative thereof.

    Abstract: A process for manufacturing a high glass transition temperature printed circuit board comprising blending a modified bismaleimide resin into a modified epoxy resin is disclosed. Particularly the material is manufactured by blending a bismaleimide resin reacted with barbituric acid and its derivative thereof and an epoxy resin with an oxazolidone ring resulting from the reaction of a polyisocyanate and an epoxy resin modified with a secondary diamine and followed by curing. The resultant product has a high glass transition temperature, a good adhesion, flame retardancy, and a low bromine content.

    Abstract: A polyimide composition for use in making polyimide/copper foil laminate that does not require an adhesive layer between the polyimide substrate and the copper foil. A polyimide precursor is first prepared from a monomer composition, which comprises a dianhydride and an imidazole-containing or benzimidazole-containing compound, or mixture thereof The polyimide precursor is then coated onto a copper foil and subsequently subject to an imidization reaction to form a polyimide/copper foil laminate, which exhibits excellent peel strength and flatness while retaining all the advantageous properties that are characteristic of polyimide resins, such as excellent mechanical strength and heat and chemical resistance. Because the polyimide/copper foil laminates disclosed in the present invention are made without the need to apply an adhesive layer, the process of manufacturing the same is greatly simplified and the cost of production therefor can be substantially reduced. Furthermore, many of the problems caused by the inferior chemical and/or physical properties of the adhesive layer are completely eliminated.

    Abstract: A proton exchange membrane comprising modified hyper-branched polymer is disclosed. The proton exchange membrane includes 85-90 wt % of sulfonated tetrafluorethylene copolymer and 15-10 wt % of modified hyper-branched polymer. The modified hyper-branched polymer comprises the bismaleimide (BMI)-based hyper-branched polymer, and parts of the chain ends of the hyper-branched polymer are sulfonated by the sulfonic compound. Also, the modified hyper-branched polymer and sulfonated tetrafluorethylene copolymer are interpenetrated to form an interpenetrating polymer. Furthermore, the modification step could be performed before or after forming the interpenetrating polymer. For example, the sulfonation is proceeded after forming the interpenetrating polymer. Alternatively, the sulfonation of the hyper-branched polymer could be proceeded before the formation of the interpenetrating polymer.
