crosslinked polystyrene meaning in Chinese

交联聚苯乙烯

The inserting method and properties of the composite materials in consist of omt and poly ( styrene - butyl acrylate ) had been researched ; the ultra - fine organic rigid particles crosslinked polystyrene ( xps ) has been synthesized by emulsion polymerization , the effect of the synthesis process on the size of organic rigid particles was discussed . the cause of the increasing mechanical properties of pp composite materials , which were strengthened and toughened with organic rigid particles and elastomer , had been investigated . the results of studying viscosity and precipitate height of sio2 nano - particles suspension showed that the sio2 nano - particles are very good dispersed by dp270 or cat 639w dispersant
通过粘度法和沉降法测定结果的一致性，说明分散剂dp270和cat639w对sio _ 2纳米粒子有较好的分散性， dp270的最佳用量为0 . 2时悬浮液粘度从35 . 1mpa ? s降为23 . 3mpa ? s ， cat639w最佳用量为0 . 4时悬浮液的粘度从35 . 1mpa ? s降为23 . 1mpa ? s ；通过研究分散剂存在下纳米粒子的苯丙乳液聚合动力学，发现纳米粒子的存在对乳液聚合有一定的缓聚作用，并讨论了乳化体系、温度、引发剂、表面处理剂以及纳米粒子用量对聚合的影响。
