A method for flocculating latex particles in a latex is characterized in that a water soluble cationic polymer containing a quaternary ammonium salt in its molecular chain is added as a flocculant to the latex. Also disclosed is a process for producing a thermoplastic resin which comprises flocculating latex particles in a latex material by adding a water soluble cationic polymer containing a quaternary ammonium salt in its molecular chain to the latex, removing freed water from the flocculated latex to obtain a wet cake and then drying the wet cake directly or after the granulation.
一种使胶乳中的胶乳颗粒絮凝的方法,其特征在于在胶乳中加入分子链中含有季铵盐的水溶性阳离子聚合物作为絮凝剂。 还公开了一种生产热塑性树脂的工艺,该工艺包括通过在胶乳中加入分子链中含有季铵盐的水溶性阳离子聚合物使胶乳材料中的胶乳颗粒絮凝,从絮凝的胶乳中除去游离水以获得湿饼,然后直接或在造粒后干燥湿饼。
