    • PURPOSE: A process for terminating a gas phase polymerization of a conjugated diene, a vinyl-substituted aromatic compound is suited for stopping a gas phase polymerization reaction of one or more dienes and/or one or more vinyl-substituted aromatic compounds. CONSTITUTION: A method for terminating a gas phase polymerization of a compound selected from the group consisting of a conjugated diene, a vinyl-substituted aromatic compound, and mixtures thereof, in a polymerization vessel in the presence of a catalyst, and optionally in the presence of an inert particulate material, comprises introducing a kill agent selected from the group consisting of an alcohol having 1 to 20 carbon atoms, an alkyl or cycloalkyl monoether each having 2 to 20 carbon atoms, ammonia, water, an alkyl or aryl amine, and mixtures thereof into the vessel in an amount sufficient to terminate polymerization; and wherein the catalyst has a metal component in which the metal is selected from the group consisting of a rare earth, nickel, cobalt, titanium, and mixtures thereof.
    • 目的:终止共轭二烯(乙烯基取代的芳族化合物)的气相聚合的方法适于停止一种或多种二烯和/或一种或多种乙烯基取代的芳族化合物的气相聚合反应。 构成:在催化剂的存在下,在聚合容器中终止选自共轭二烯,乙烯基取代的芳族化合物及其混合物的化合物的气相聚合的方法,并且任选地存在 的惰性颗粒材料,包括引入选自具有1至20个碳原子的醇,具有2至20个碳原子的烷基或环烷基单醚,氨,水,烷基或芳基胺的杀死剂,和 其混合物以足以终止聚合的量装入容器中; 并且其中所述催化剂具有其中所述金属选自稀土,镍,钴,钛及其混合物的金属组分。
