    • The invention relates to a method and a device for reprocessing a polymer-containing latex dispersion, particularly a latex dispersion containing acrylonitrile butadiene styrene polymers, into polymer powder. In the claimed method, the latex is coagulated under the effect of heat by adding, thoroughly mixing, and/or shearing a coagulating agent, especially an acid and/or an electrolyte, the volatile auxiliary agents and remaining monomers are optionally removed using steam distillation, the obtained suspension is cooled in a cooling step, and the moist polymer is mechanically separated and/or thermally dried to polymer powder in a subsequent step. Said method is characterized in that the cooling step comprises indirect cooling by means of a heat exchanger.
    • 本发明涉及一种用于含聚合物的胶乳分散体,特别是含有聚合物粉末的胶乳分散体的丙烯腈 - 丁二烯 - 苯乙烯聚合物的处理的方法和装置。 在本发明方法,特别是一种酸和/或电解质是通过将混合和/或热的作用下,胶乳的剪切下凝固凝结剂制备,任选地,所述易失性助剂和残留单体通过蒸汽蒸馏,在冷却步骤中所得到的悬浮液中除去 冷却和机械湿聚合物在随后的步骤中分离和/或热干燥,得到聚合物粉末。 该方法的特征在于,所述冷却步骤包括通过热交换器的装置的间接冷却。
