Development and Prospects of Biodegradable Plastics Industry in China
The emergence of traditional plastic products has greatly enriched people's lives,but also brought about the problem of"white pollution",and destroyed the normal ecological balance of land and sea.In order to solve the environmental problems caused by disposable plastic products,the development of biodegradable plastics has gradually become a hot topic in the field of polymer research.This paper starts from the types,properties and degradation principles of biodegradable plastics,based on the technical advantages of petrochemical and coal chemical industries,the technical routes of fossil based synthesis of five kinds of biodegradable plastics were introduced,including poly-butylene adipate terephthalate(PBAT),poly-butylene succinate(PBS)/poly-butylene succinate adipate(PBSA),poly-glycolic acid(PGA),poly-caprolactone(PCL)and propylene carbonate(PPC).And,the future of biodegradable plastics was prospected.
