    • PURPOSE: A removing method of residual monomers in slurry is provided to minimize the generation of coagulum and foam and to maximize the removing effect of residual monomer, by optimally controlling the size of bubbles generated by bubbling. CONSTITUTION: A removing method of residual monomers of the slurry comprises a coagulation step and an aging step, and a step of removing residual monomers by using bubbles of which size is 5-500 micron, generated by bubbling in polymer slurry. The coagulation step and the aging step are not divided, but operated at the same time in one reactor. The bubbling is generated by inserting of insert gas or air. The solid content of the polymer slurry is 25-60wt%.
    • 目的:提供浆料中残留单体的去除方法,以最大限度地控制发泡产生的气泡的大小,最大限度地减少凝结物和泡沫的产生,并使残留单体的除去效果最大化。 构成:浆料的残余单体的除去方法包括凝固步骤和老化步骤,以及通过使用通过在聚合物浆料中鼓泡产生的尺寸为5-500微米的气泡除去残余单体的步骤。 凝固步骤和老化步骤不分开,但在一个反应​​器中同时操作。 通过插入气体或空气产生起泡。 聚合物浆料的固体含量为25-60wt%。
