摘要

In this interview

the latest achievements in the depolymerization and functionalization of super engineering plastics into valuable monomers were summarized

especially for PPS

sulfone-containing poly(arylene ether)s

and PEEK. The designs and developments of innovative and more sustainable strategies for the depolymerization of super engineering plastics are highly desirable.

Abstract

Chemical recycling/upcycling of plastics has emerged as one of the most promising strategies for the plastic circular economy

enabling the depolymerization and functionalization of plastics into valuable monomers and chemicals. However

studies on the depolymerization and functionalization of challenging super engineering plastics have remained in early stage and underexplored. In this review

we would like to discuss the representative accomplishments and mechanism insights on chemical protocols achieved in depolymerization of super engineering plastics

especially for poly(phenylene sulfide) (PPS)

poly(aryl ether)s including poly(ether ether ketone) (PEEK)

polysulfone (PSU)

polyphenylsulfone (PPSU) and polyethersulfone (PES). We anticipate that this review will provide an overall perspective on the current status and future trends of this emerging field.
