乳液聚合方法
摘要：
本发明涉及一种使用包含还原剂和氧化剂的氧化还原引发剂的乳液聚合方法，其中将单体混入载液如水中以制备预乳液，然后将该预乳液供入包括一个或多个循环回路、出口和用于在该循环回路内循环反应器进料的循环泵的反应器中，其特征在于将还原剂在混入反应器进料中之前加入预乳液中并将氧化剂例如经由水相进料混入反应器进料中。
摘要（英）：

AN EMULSION POLYMERISATION PROCESS USING A REDOX INITIATOR COMPRISING A REDUCTANT AND AN OXIDANT, WHEREIN MONOMERS ARE MIXED INTO A CARRIER LIQUID, E.G. WATER, TO MAKE A PRE-EMULSION, WHICH IS THEN SUPPLIED TO A REACTOR COMPRISING ONE OR MORE CIRCULATION LOOPS, AN OUTLET, AND A CIRCULATION PUMP FOR CIRCULATING A REACTOR CHARGE WITHIN THE CIRCULATION LOOP, CHARACTERISED IN THAT THE REDUCTANT IS ADDED TO THE PRE-EMULSION BEFORE IT IS MIXED INTO THE REACTOR CHARGE AND THE OXIDANT IS MIXED INTO THE REACTOR CHARGE, E.G., VIA THE WATER-PHASE FEED.
