Described herein is a semi-continuous process for producing a polymer water-in-oil emulsion which process comprises: (a) combining: (i) an aqueous solution comprising at least one water-soluble monomer and (ii) a mixture comprising a hydrophobic liquid, a hydrophobic monomer and an oil-soluble surfactant; (b) homogenizing the mixture from (a) to form a water-in-oil emulsion; (c) deoxygenating said homogenized water-in-oil emulsion; (d) continually adding the homogenized water-in-oil emulsion to a reactor while adding thereto a deoxygenated initiator solution; (e) heating the mixture from (d) under polymerization conditions so as to form a polymer water-in-oil emulsion, and (f) recovering a polymer water-in-oil emulsion.
本文描述了一种半连续的生产聚合物水包油乳液的工艺,该工艺包括以下步骤:(a)将:(i)至少含有一种水溶性单体的水溶液和(ii)包含疏水液体、疏水单体和油溶性表面活性剂的混合物混合;(b)均质化(a)中的混合物以形成水包油乳液;(c)脱氧化均质化的水包油乳液;(d)在向其中加入脱氧化的引发剂溶液的同时,不断将均质化的水包油乳液加入反应器中;(e)在聚合条件下加热(d)中的混合物,以形成聚合物水包油乳液;(f)回收聚合物水包油乳液。
