Halogen-Containing Aminimide Compounds as Tire Cord Adhesives

Abstract Aminimides derived from dibasic acids such as sebacic acid have proven to be very good adhesives when used in the first dip of a two-dip tire cord system. These aminimide materials have the advantage of being water soluble for easy application. They give effective adhesion of rubber to polyester tire cord. Although they offer process advantages, their performance is only approximately as good as present commercial art. It would be a further advantage if aminimides for tire cord bonding were improved over the best tire cord adhesive. Consequently, a means to effect bonding improvement was sought. Halogenated aminimides were prepared to effect tire cord bonding improvement to polyester cord. Various compounds derived by synthesis procedures for polyhalo aromatic or norbornene aminimide compounds were prepared. The preparations were designed so that the starting materials were readily available. The aminimide precursors avoided base-displaceable halogen because strong base is needed to make aminimid...
