化学工业战线上捷报频传,继“塑料王”聚四氟乙烯之后,又一种新型的塑料——改性聚苯乙烯,已经在兰州化学工业公司试制成功,并且成批生产。由焦炉气或石油废气中制得的乙烯和炼焦的副产品——苯化合,制成苯乙烯,几万或几十万个苯乙烯分子相互联接成长鏈型的大分子,就变成了聚苯乙烯。聚苯乙烯经过进一步加工处理,性质进一步改善就得到改性聚苯乙烯。早在一百多年前,人们就制得了苯乙烯——一种浓香扑鼻的油状液体。它在通常情况下就会自行聚合成固体,由此发现了聚苯乙烯。
On the chemical industry front, news reports have been repeated. Following the “Plastic King” PTFE, another new type of plastic, modified polystyrene, has been successfully tested at Lanzhou Chemical Industry Co., Ltd., and has been produced in batches. From the coke oven gas or petroleum gas produced by the ethylene and coke by-products - benzene, made of styrene, tens of thousands or hundreds of thousands of styrene molecules linked to each other to form a chain of macromolecules, it becomes a poly Styrene. Polystyrene is further processed to improve the properties of modified polystyrene. As early as a hundred years ago, people had made styrene, an aromatic oily liquid. It will normally polymerize itself into a solid, from which polystyrene is found.
