废聚酯解聚技术研究现状

Research Status of Depolymerization Technology of Waste PET

聚酯是由对苯二甲酸与乙二醇发生聚合反应得到的高分子物质聚对苯二甲酸乙二酯(PET),被广泛应用于合成纤维、食品包装、薄膜制品等方面。每年产生的废聚酯数量巨大,对环境的污染严重。本论文主要讲述了利用解聚的方法回收合成聚酯的单体的新的方法和技术。

Polyester is a kind of high molecular material,polyethylene terephthalate(PET),which is produced by the polymerization of terephthalic acid and glycol.It is widely used in synthetic fiber,food packaging,film products and so on.The amount of waste polyester produced every year is huge,which causes serious environmental pollution.In this paper,a new method and technology for the recovery of monomers of synthetic polyester by depolymerization is introduced.
