  • Chlorine-containing polymer vulcanizing composition
    Publication number: 20030153652
    Abstract: The present invention provides a chlorine-containing polymer vulcanizing composition with improved preservation stability. The present invention is a chlorine-containing polymer vulcanizing composition obtained by blending (a) a zeolite compound, (b) a vulcanizing agent, and (c) an optional organic vulcanization accelerator. The zeolite compound can be natural zeolite, an A-type, X-type, or Y-type synthetic zeolite, a sodatite, natural or synthetic mordenite, ZSM-5, or a metal substitution product thereof. The zeolite compound is preferably an activated zeolite compound. With respect to 100 parts by weight of chlorinated polyethylene, (a) preferably 0.5 to 30 parts by weight, more preferably 5 to 25 parts by weight, of the zeolite compound, (b) preferably 0.1 to 5 parts by weight, more preferably 0.5 to 3 parts by weight, of the vulcanizing agent, and (c) preferably 0.5 to 3 mol, more preferably 0.7 to 1.5 mol, of the vulcanization accelerator with respect to 1 mol of (b) the vulcanizing agent are blended.
