阅读说明：本技术 具有门尼粘度稳定性的卤化弹性体及其制备方法 (Halogenated elastomers having Mooney viscosity stability and process for their preparation ) 是由 顾乐明 T·R·巴比 J·E·施米格 于 2018-03-28 设计创作，主要内容包括：本文提供了改进溴化弹性体的门尼稳定性的方法,其包括：用中和剂和水中和溴化弹性体流出物来形成包含烃溶剂的中和的流出物；从该中和的流出物中除去所述溶剂来形成溴化弹性体浆体；和从该溴化弹性体浆体中分离溴化弹性体,其中在所述除去步骤之前,可以一起或者分别加入包含胺官能化的受阻胺稳定剂(HAS)和除酸剂的门尼稳定剂包。所述除酸剂可以包含可质子化原子,其的pKa大于HAS氮原子的pKa。所分离的溴化弹性体在～80℃～7天之后Δ门尼可以不大于大约10个门尼单位。使用这种方法可以制造稳定的溴化弹性体组合物,和由那些组合物可以制造制品。(Provided herein is a method of improving the mooney stability of a brominated elastomer, comprising: neutralizing the brominated elastomer effluent with a neutralizing agent and water to form a neutralized effluent comprising a hydrocarbon solvent; removing said solvent from the neutralized effluent to form a brominated elastomer slurry; and separating the brominated elastomer from the brominated elastomer slurry, wherein a Mooney stabilizer package comprising an amine functionalized Hindered Amine Stabilizer (HAS) and an acid scavenger can be added together or separately prior to the removing step. The acid scavenger may comprise a protonatable atom having a pKa greater than the pKa of the HAS nitrogen atom. The isolated brominated elastomer may have a delta mooney of no greater than about 10 mooney units after-80 ℃ to 7 days. Stable brominated elastomer compositions can be made using this method, and articles can be made from those compositions.)
