TI  - Upcycling of semicrystalline polymers by compatibilization: mechanism and 
      location of compatibilizers.

AB  - With the continuous increase of global plastics production, there is a demand to 
      develop energy efficient processes to transform mixed plastic wastes into new 
      products with enhanced utility - a concept that is often referred to as 
      upcycling. Compatibilization is one of the most promising strategies to upcycle 
      communal waste plastics. In this work, poly(ethylene terephthalate) (PET) and 
      high-density polyethylene (HDPE), both widely used semicrystalline packaging 
      polymers, are used as the target polymer blend. We systematically evaluate and 
      compare three commercial ethylene copolymer based compatibilizers, ELVALOY AC 
      2016 Acrylate Copolymer (EAA), ELVALOY PTW Copolymer (PTW), and SURLYN 1802 
      Ionomer (Surlyn). They represent different compatibilization mechanisms. 
      Furthermore, this work tackles a challenging question: where the compatibilizers 
      are located in the blend. We discover that the location of the compatibilizer 
      molecules can be predicted by comparing the crystallinity change of PET and HDPE 
      in binary and ternary systems. Gaining this knowledge will facilitate root cause 
      analysis of an ineffective compatibilizer and guide the design strategy to 
      upcycle commingled waste plastics.
