一种用于制造可膨胀苯乙烯紧合物粒子之方法，其具有改良之加工特性系包含: i)制造含有所并用之2至20%膨胀剂之可膨胀苯乙烯聚合物粒子; ii)将此等粒子覆盖抗静电剂，其数量为少于l重量%； iii)在混合设备中将粒子剧烈地摩擦，借由简单的机械摩擦而在短时间内加热粒子之表面; iv)从混合设备排出借此所处理之粒子。

Process for the production of expandable particles of styrene polymers, having improved processability characteristics, which comprises: (i) producing expandable particles of styrene polymers containing from 2 to 20% of an expanding agent incorporated; (ii) covering these particles with an antistatic agent in a quantity of less than 1% by weight; (iii)vigorously frictioning the particles in a mixing apparatus in order to heat their surface, in a short time, by simple mechanical friction; (iv) discharging the particles thus treated from the mixing apparatus.
