The catalyst system is very stable at ambient temperature and its stability is enhanced by addition of small amount of styrene monomer during preparation.
该催化体系有较高的低温稳定性,在陈化时加入少量苯乙烯单体能增强其稳定性。
The PS hikes can be chalked up to an improving price market for benzene feedstock, which is used to make styrene monomer .
的PS可以用粉笔加息行动的改善市场价格苯原料,这是用于制造苯乙烯单体。
The optimum conditions for the technological process of recovering styrene monomer from foamed polystyrene were found.
通过实验对发泡聚苯乙烯热解回收苯乙烯单体的工艺流程提出了优化操作条件。
Crude product by simple distillation, styrene recovery was 89.41% of total styrene monomer purity of 99.9%, and catalyst recycling, the effect is better.
