Abstract: Emulsion polymers, formed by reacting a monomer phase with a water phase, are generated in a tubular reactor having a controlled loop section (10) to give a partially developed product, such as one having 5-20% unreacted monomer, and a controlled plug section (11), which is preferably larger than the loop section by a factor of at least two, to give a fully developed product. Means (19, 17) exist to cool both loop and plug sections but preferably to keep the plug section at a higher temperature, which temperature can be zoned. Supplementary reactants may be introduced into the plug section. One such reactant may be a monomer to encase particle cores formed in the loop section with shells. An expansion agent may be included in the reactants which is dormant in the loop section but active in a higher temperature plug section.

Abstract translation: 通过使单体相与水相反应而形成的乳液聚合物在具有受控环部分（10）的管式反应器中产生，得到部分显影的产物，例如具有5-20％未反应单体的管状反应器和控制塞 部分（11），其优选大于循环部分至少两倍，以产生完全展开的产物。 存在用于冷却环和塞部分的装置（19,17），但优选地将塞部分保持在更高的温度，该温度可以被划定。 补充的反应物可以被引入到塞子部分中。 一种这样的反应物可以是用壳包裹在环部分中形成的颗粒核的单体。 在循环部分中休眠的反应物中可以包含膨胀剂，但是在较高温度的塞子部分中起作用。
