  The present invention provides a method for producing expandable thermoplastic polymer particles which comprises conducting polymerization by adding a polymerizable monomer either continuously or intermittently to thermoplastic polymer particles having a uniform particle size suspended in water,characterized in that an amide compound is added when the added amount of the polymerizable monomer is not more than one half of the total amount to be added in the course of polymerization and resulting polymer particles are impregnated with an easily volatile blowing agent after completion of addition of the amide compound and the polymerizable monomer. According to the present invention, expandable thermoplastic particles which are capable of giving cells, fine and uniform in size, are obtainable even by expanding immediately after production without any aging period.

  本发明提供了一种生产可膨胀热塑性聚合物颗粒的方法，该方法包括通过连续或间歇地向悬浮在水中的粒度均匀的热塑性聚合物颗粒中加入可聚合单体进行聚合，其特征在于，当加入的可聚合单体量不超过聚合过程中加入总量的一半时，加入酰胺化合物，在完成酰胺化合物和可聚合单体的加入后，用易挥发性发泡剂浸渍得到的聚合物颗粒。根据本发明，即使在生产后立即膨胀，也无需任何老化期，即可获得可膨胀热塑性粒子，这种粒子能够形成细小均匀的细胞。
