  • Process for preparing novel moisture-curable hot-melt adhesive compositions
    Patent number: 5324778
    Abstract: Novel crosslinkable hot-melt adhesive compositions, curable by atmospheric moisture, include (i) the prepolymerizate of an hydroxylated ethylene/vinyl acetate copolymer with a stoichiometric excess of a polyisocyanate, e.g., a diisocyanate, such prepolymerizate containing an effective crosslinkable amount of free isocyanate functional groups, and, optionally, (ii) an adhesive tackifying resin.
    Type: Grant
    Filed: November 5, 1992
    Date of Patent: June 28, 1994
    Assignee: Atochem
    Inventors: Jacques Boutillier, Yves Lermat

  • Hot melt adhesive of hydroxyl-functional ethylene-vinyl acetate and blocked polyisocyanate
    Patent number: 5064902
    Abstract: A composition for a cross-linkable hot melt adhesive is provided and is formed by an ethylene-vinyl acetate copolymer containing primary hydroxyl functions and a blocked polyisocyanate. This composition when associated with a tackifying resin which can also serve as blocking agent of the polyisocyanate, is a cross-linkable hot melt adhesive. The adhesive is used at a temperature at least equal to splitting temperature of the isocyanate functions of the polyisocyanate. The temperature at which such adhesives retain adherence can reach about 200.degree.-220.degree. C.

  • Adhesive compositions
    Patent number: 4806582
    Abstract: This invention is directed to an adhesive composition comprising:(a) a copolymer of ethylene or a mixture of ethylene and another ethylenically unsaturated polymerizable monomer with a hydroxyalkyl ester or an epoxyalkyl ester, and(b) an organometallic compound of lead, tin, or titanium.
