  • Multilayered container and method for making
    Patent number: 4940616
    Abstract: Anti-gas permeation property and impact strength of a container such as a bottle which is made of polyethylene terephthalate resin by biaxially orienting blow molding are improved by using a multilayered structure of the polyethylene terephthalate and the other polyester of a dicarboxylic acid component containing a specific amount of isophthalic acid and a glycol component. The container is made preferably by preparing a preform which is a laminate of the polyethylene terephthalate and the other polyester in the molten state under pressure, and by biaxially orienting blow molding the preform.
    Type: Grant
    Filed: May 12, 1988
    Date of Patent: July 10, 1990
    Assignee: Mitsui Petrochemical Industries

  • Five-component copolyester, process for preparation thereof, and shaped articles thereof
    Patent number: 4692506
    Abstract: A five-component copolyester not described in the prior art literature which comprises at least five components, i.e. (a) two aromatic dicarboxylic acid components composed of a major amount of an isophthalic acid component and a minor amount of another dicarboxylic acid component, (b) a diol component composed of an ethylene glycol component and optionally another diol component, (c) an aromatic monohydroxy-monocarboxylic acid component and (d) a polyfunctional compound component having at least three functional groups. The copolyester has excellent melt moldability, mechanical strength, transparency and gas-barrier property in a well balanced combination, and shows improved properties over conventional copolyesters containing a major amount of isophthalic acid as a dicarboxylic acid component.

  • Process for the formation of a polyolefin coating layer onto a metal surface
    Patent number: 4048355
    Abstract: A process for forming a polyolefin coating layer onto a surface of a metal which comprises coating an uncured epoxy resin layer onto the surface of a metal and melt-bonding a polyolefin modified with an unsaturated carboxylic acid or an anhydride thereof onto the uncured epoxy resin layer coated onto said metal surface. The coating layer has a high bonding strength and excellent water resistance, especially resistance against brine.
