  • Patent number: 5858550
    Abstract: Multilayered films produced by coextruding or laminating films comprised of at least one layer of polymethylpentene, at least one layer of a polyamide and an intermediate polymeric adhesive layer. The polyamide layer allows the polymethylpentene layer to be stretched up to 6 times its original length. Such a high orientation ratio for the mulitlayered film increases the mechanical strength and toughness properties of the film. The mulitlayered films are suitable for use as release films for high temperature composite applications such as printed circuit boards.

  • Patent number: 5840829
    Abstract: An adhesive is provided for bonding cyanate ester composite parts together which is also plateable with metal once chemically etched. The adhesive comprises a polymeric matrix and a filler of cyanate ester polymer. The polymeric matrix comprises at least one polyepoxide resin and a curing agent, while the cyanate ester polymer filler is present in the adhesive as a powder. In practice, the present adhesive is applied to the surface of cyanate ester composite articles to be bonded and is allowed to cure at room temperature. Thereafter, the surface of the assembly is chemically etched and then plated with metal. The present adhesive enable the complete coverage of the cyanate ester composite assembly with the plated metal, including the adhesive bondlines.

  • Patent number: 5658414
    Abstract: An improved method is described for the fusing, joining or seaming of cellulosic materials. The method utilizes a solution of selected organometallic compounds or metal oxides to rapidly crosslink opposing, overlapping cellulosic surfaces to provide secure seams. Enhanced seam strength is achieved by a subsequent moisture treatment. The tubular cellulosic casings are well-suited for the manufacture of sausages and sausage-like products. The seams according to this invention have exceptionally high shear strength and wet strength.
