  • Method for preparing an extrudable priming mixture containing modified karaya gum
    Patent number: 4001060
    Abstract: A method of treating karaya gum to stabilize it so that it is less sensitive to the presence of certain priming compositions and will exhibit, when used with priming compositions, improved extrusion characteristics and rheological stability. The karaya gum is suspended in an anhydrous alcohol and treated with a reagent which is soluble in the alcohol whereby the gum renders a priming composition suitable for extrusion for mechanically charging primers.
