    Abstract: An improved method for preparing copper clad laminates from a copper substrate without a conventional or infrared oven. The method contains the steps of: (a) preparing a precursory coating composition which can be subsequently cured to become polyimide; (b) coating the precursory coating composition on a copper substrate; and (c) exposing the precursory coating composition to an infrared heater provided in an infrared curing apparatus. The infrared heater is selected such that it emits infrared rays of wavelengths correponding to the absorption spectrum of the precursory coating composition. A plurality of infrared heaters can be provided in the infrared curing apparatus, each can be designed to have a different effective heating length and/or operated at a uniquely predetermined surface temperature for optimum energy efficiency. Preferably, the precursory coating composition contains an upper layer consisting essentially of polyamic acid and a lower layer disposed between the upper layer and the copper substrate, the lower layer being a blended mixture of the polyamic acid and a modified bismaleimide.

    Abstract: An improved polyimide-based coating composition comprising a polyimide upper layer and a polyimide-modified bismaleimide lower layer for use as a coating on metal substrate, such as an electrolytic copper foil. The polyimide are prepared from reactions between diamines, such as p-phenylene diamine and 4-4'-diaminodiphenyl ether, and dianhydrides, such as 3,3',4,4'-benzophenone tetracarboxylic dianhydride and biphenyl-3,3',4,4'-tetracarboxylic dianhydride. The modified bismaleimide can be prepared from reacting an N,N',4,4'-diphenyl bismaleimide with a barbituric acid or its derivative. A double-layered extrusion coating technique having a double-layered extrusion die is utilized to apply the coating composition onto the metal substrate. The final laminated products show improved peel strength between the polyimide coating and the substrate, as well as improved dimensional stability and surface flatness thereof.

    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.

    Abstract: A resin composition useful in the fabrication of circuit boards comprises (i) 1˜15 W % of bismaleimide modified by barbituric acid (BTA) and its derivatives; and (ii) 20˜50 wt % of polyphenylene ether (PPE) chain-broken in a phenol resin; wherein the phenol resin is terpene phenol resin or dicyclopentadiene phenol resin. Other additives, such as curing agent, catalyst or inorganic particle additive can be added as well, based on requirements. According to the invention, terpene novolac resin and initiator (peroxide) are added in polyphenylene ether so that molecules are rearranged to form a PPE resin having lower molecular weight and higher crosslinking density. Furthermore, BMI/epoxy resin/PPE are combined in different weight percentages. Semi-interpenetrating polymer network structures are thus formed. Consequently, Tg and resistances both to heat and solvent of the resin are increased.

    Abstract: A polyimide/copper foil laminate prepared using a polyimide composition 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 ahsesive 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: Disclosed is a novel linear urethane-amide-imide copolymer composition obtained from first reacting X mols of diol compound, which had been dissolved in an inert organic solvent, with Y mols of diisocyanate compound at room temperature to produce an intermediate reaction product, followed by reacting the intermediate reaction product with Z mols of trimellitic anhydride at elevated temperatures, wherein Y is greater than X (i.e., the amount of diisocyante groups is in excess) and approximately equals the sum of X plus Z. The polyurethane copolymer composition obtained from this process contains urethane, amide and imide groups on the polymer backbone, exhibits excellent mechanical and electric properties and heat resistance, and does not suffer from the phase separation problems observed from polyurethane-polyamideimide blends.
