Low-density (LD) and high-density polyethylene (HDPE), recycled or not, incorporates up to 7 wt% of ester groups after reacting either with ethyl diazoacetate (EDA) under catalytic and solvent free-reaction conditions, or with maleic anhydride (MA) and acrylates (AC) under catalytic radical conditions. The resulting upcycled polyethylene esters are hydrolytically stable at extreme pH (0-14) and can be further transformed into carboxylic acids, carboxylates, other esters and amides.
低密度（LD）和高密度聚乙烯（HDPE），无论是否回收利用，在无催化剂和无溶剂反应条件下与重氮乙酸乙酯（EDA）反应，或在催化自由基条件下与马来酸酐（MA）和丙烯酸酯（AC）反应后，都能引入高达7 wt%的酯基。所得的升级循环聚乙烯酯在极端pH值（0 - 14）下具有水解稳定性，并且可以进一步转化为羧酸、羧酸盐、其他酯类和酰胺。
