In the first step of the process, an excess of hydrogen cyanide is reactive with an aryl diisocyanate. The excess hydrogen cyanide promotes polymerization and avoids the reaction of the imino hydrogen on the heterocyclic range with the diisocyanate to form cross linkage and associated gel formation. In the second step, a stoichiometric amount of diisocyanate is added to react with the excess hydrogen cyanide and one hydroxyl of a phenolic dihydroxyl end capping group. In the final third step, the dihydroxyl end capping group is added and the remaining diisocyanate reacts with one of the two phenolic hydroxyls on the end capping group.

  • Patent number: 5097010
    Abstract: Thermally-reversible polymer compositions are obtained by reacting compounds with isocyanate and labile-hydrogen functionality. High-performance characteristics are incorporated into the polymer by using polyimide, aromatic polycarbonate, aromatic polyester, polyphenylene sulfide, and poly(parabanic acid) oligomers. Low-temperature flexibility and toughness are imparted to the polymers by using prepolymers such as polycaprolactone diols, polytetramethylene ether glycols and polyaliphatic carbon diols. Ionic bonding and liquid-crystal functionality may also be incorporated into the compositions. The compositions are useful as hot-melt adhesives, coatings, and moldings and in injection reaction molding applications and composite and laminate fabrication.

  • Patent number: 5021509
    Abstract: The present invention provides for an improved butyl rubber composition which exhibits improved adhesion to pre-treated polyester textile materials, while at the same time important physical properties of cured butyl rubber such as modulus, tensile strength and elongation are maintained or even enhanced. The vulcanizable composition of the invention is based on a blend of butyl rubber and minor amounts of a copolymer of ethylene with a lower alkyl acrylate or methacrylate, or a terpolymer of ethylene, a lower alkyl acrylate or methacrylate and acrylic or methacrylic acid. The composition of this invention exhibits improved adhesion to pre-treated polyester textile materials.The invention also relates to laminates of the butyl rubber compositions of this invention with polyester textile materials such as yarns and woven fabrics.
