    • The invention relates to a continuous process for the preparation of amphiphilic graft polymers, wherein a vinyl ester component (B) composed of vinyl acetate and/or vinyl propionate (B1) and, if desired, a further ethylenically unsaturated monomer (B2), is polymerized in the presence of a polyalkylene oxide (A), a free radical-forming initiator (C) and, if desired, an additive (D), at a mean polymerization temperature at which the initiator (C) has a decomposition half-time of from 1 to 500 min, in at least one tubular reactor segment with a feed side and an outlet side, through which the reaction mixture comprising at least a part of component (A) to (C), and if desired (D), streams, a tubular reactor segment and the use of the inventive amphiphilic graft polymer. The invention further relates to an inventive amphiphilic graft polymer and the use thereof.
    • 本发明涉及制备两亲性接枝聚合物的连续方法,其中由乙酸乙烯酯和/或丙酸乙烯酯(B1)组成的乙烯基酯组分(B)和如果需要,另外的烯键式不饱和单体(B2)是 在聚亚烷基氧化物(A),自由基形成引发剂(C)和根据需要的情况下,在引发剂(C)具有分解半衰期的平均聚合温度下,如果需要,添加剂 在至少一个具有进料侧和出口侧的管状反应器段中,反应混合物通过该混合物至少包含组分(A)至(C)和(如果需要的话)(D), 流,管式反应器段和本发明的两亲接枝聚合物的用途。 本发明还涉及本发明的两亲性接枝聚合物及其用途。
