    摘要： Bonded composites of discontinuous organic fiber and vulcanized matrix are prepared by treating the fiber to reduce fiber to fiber interaction, dispersing the treated fiber and bonding ingredients into vulcanizable elastomeric matrix, positioning the fiber therein taking suitable precautions to minimize fiber breakage during the dispersing and positioning of the fiber, and vulcanizing the mixture to produce a bonded composite in which the organic fiber has an aspect ratio of at least about 20 but not more than about 350.

    摘要： A class of 2-aminobenzoazoles is described which is used with primary accelerators to enhance the vulcanization rate of rubber. The new vulcanization activators are characterized by the formula

    IN WHICH Y is oxygen or sulfur, X is hydrogen, alkyl, alkoxy, nitro, halo or hydroxy, and n is one or two; when n is one R is hydrogen, alkyl, aryl, cycloalkyl, aralkyl, hydroxyalkyl, or alkenyl; when n is two R is alkylene. The conjoint use of the new activators with thiazole accelerators is particularly advantageous since the vulcanization rate is increased without affecting the processing safety of the vulcanizable composition.
