  • Patent number: 5439541
    Abstract: This invention provides crosslinked copolyester adhesives, rigid foams, protective coating, matrices for composites and dielectric for electrical circuits, and methods for making crosslinked copolyester adhesives, rigid foams, protective coatings, matrices for composites and dielectrics for electrical circuits. Two or more adherends may be bonded together using a crosslinked copolyester adhesive by first combining at least one oligomer having carboxylic acid end groups with at least one oligomer having ester end groups, where at least one of the oligomers is branched, to form a mixture. Then, the mixture is applied to the adherends to be bonded and the mixture on the adherends is cured. Next, the adherends are positioned such that the cured mixtures contact and the contacted mixtures heated to form a bond between the cured mixtures.

  • Patent number: 5368942
    Abstract: A method of adhering two substrates comprising covalently modifying a smooth surface of at least one of the substrates is disclosed. A smooth surface of a first substrate is covalently modified to present groups, which are one member of an acid-base pair (MABP groups). The covalently modified surface is contacted with a smooth surface of a second substrate. The smooth surface of the second substrate presents groups are the acid-base complement of the MABP groups (MABP complements). The interaction of the MABP groups with the MABP complements results in the formation of an adhesive bond between the smooth surface of the second substrate and the covalently modified surface of the first substrate. The MABP complements may inherently be present on the surface of the second substrate or the surface of the second substrate may be modified to present the MABP complements.

  • Patent number: 5364703
    Abstract: The present invention is directed to improving the peel strength of copper foil laminated to polyetherimide substrates which optionally are reinforced. The improvement in process comprises coating one side of the copper foil with an adhesive composition, placing the coated side of the copper foil in contact with pre-formed polyetherimide substrate, and heat-pressing the resulting build-up to form a cured laminate of improved peel strength. The adhesive composition utilized comprises a blend of a polyvinyl butyral resin; one or more resole resins, and an organic solvent. Heat-pressing conditions comprise a temperature ranging from about 450.degree. to 550.degree. F. and pressing conditions ranging from about 100 to 700 psi. Within this temperature/pressure range, the adhesive-coated copper foil mated with the pre-formed polyetherimide substrate yields desired peel strengths without inducing excessive flow of the polyetherimide substrate, i.e. maintaining a pre-desired thickness .+-.7.5%.

  • Patent number: 5348607
    Abstract: A mixture for affixing dice to a substrate includes a thermoplastic polyimide, a solvent for the polyimide, and a solvent which does not dissolve the polyimide but adds thixotropicity to the mixture. The mixture is applied to the substrate, the dice are placed thereon, and the solvents are evaporated to bond the dice to the substrate. The bond is radiation hard and exhibits high shear pull strength. A poor solvent for the polyimide, sprayed over the dice and exposed portions of die attach material, causes some polyimide to precipitate out of solution in the exposed portions of die attach material to form a grid that extends between the dice and prevents the dice from "swimming together" during high temperature processing. In a solvent die-attachment method, the substrate is first coated with a mixture of die attach material, and the mixture is dried. Spraying a solvent over the die attach material causes the material to soften so that the dice applied thereto may adhere.
