Process for the preparation of an elastomeric polymer having randomly distributed conjugated diolefin moieties in which a part, or all, of the moieties comprising the conjugated diolefin have at least one double bond of the pair of double bonds comprising the conjugated diolefin unsaturation located in the chain of carbon atoms comprising the polymer backbone, or are in a ring of carbon atoms integral with said chain of carbon atoms, comprises heating a reaction mixture comprising a solution of a halogenated butyl rubber in a non-reactive solvent with a reagent comprising the reaction product of zinc oxide or zinc hydroxide and a Cs to C18 acyclic or alicyclic carboxylic acid, prepared in situ in the non-reactive solvent from the said zinc compounds and acids, in a reaction zone while continuously removing water from said reaction zone by physically entraining water from the reaction zone.
用于制备具有随机分布的共轭二烯烃分子的弹性聚合物的工艺,其中共轭二烯烃的部分或全部分子在构成聚合物骨架的碳原子链中具有构成共轭二烯烃不饱和度的一对双键中的至少一个双键,或者位于与所述碳原子链为一体的碳原子环中、包括在反应区加热反应混合物,该混合物包括卤化丁基橡胶在非反应性溶剂中的溶液与试剂,试剂包括氧化锌或氢氧化锌与 Cs 至 C18 无环或脂环羧酸的反应产物,该反应产物由上述锌化合物和酸在非反应性溶剂中就地制备,同时通过从反应区物理夹带水不断从所述反应区除去水。
