A study on the synthesis, modification and current market status of PBAT

Abstract

With the increasing awareness of environmental protection, the problem of "white pollution" caused by waste plastics has become more and more important to all countries, and the restriction of plastic and plastic ban has become a global consensus, which has ushered in a good opportunity for the biodegradable plastic industry. Polybutylene adipate-butylene terephthalate (PBAT) is one of the most widely used biodegradable plastics at present. This paper mainly introduces the synthesis, modification and current market status of PBAT. At present, the synthesis process of PBAT mainly adopts direct esterification method, often blended with other resins for modification, and the prepared products are used in the field of film bags. In recent years, the production capacity of PBAT has grown significantly, mainly in China.
