Disclosed are staged emulsion polymers comprising a crosslinked first stage polymer and a subsequently polymerized linear or slightly crosslinked second stage polymer segment. The staged emulsion polymers possess a dual activation mechanism and provide desirable rheological, clarity, and aesthetic properties in aqueous and aqueous surfactant containing compositions.
所公开的分阶段乳液聚合物包括交联的第一阶段聚合物和随后聚合的线性或轻微交联的第二阶段聚合物段。这种分级乳液聚合物具有双重活化机制,在水性和含水表面活性剂组合物中具有理想的流变性、透明度和美观特性。
