摘　　要： 聚苯乙烯是应用最广的热塑性塑料之一。聚苯乙烯泡沫塑料在工业上应用广泛,但由于其在自然界中,既不腐烂,也不易被微生物降解,因此,容易形成白色污染。介绍了聚苯乙烯的催化降解,并得出了使用催化剂不同,降解产品也不同的结论。此外,还指出采用高效、价廉的催化剂,对废旧聚苯乙烯进行高效、清洁的回收和利用,将会极大的促进聚苯乙烯产业的发展。 Polystyrene is one of the most widely used thermoplastic plastics. Polystyrene foamed plastic is widely used in the industry. However, foamed polystyrene plastic does not decompose and is not easy to be degraded by microorganism in the nature. Therefore, white pollution is formed. It mainly introduced the catalytic degradation of polystyrene and drew a conclusion that degradation, products vary with different catalysts. Furthermore, it pointed out that through the use of high efficient and low-cost catalysts, by reasonably recovering and making use of PS wastes, the PS industry will be develonod further.
