Depolymerization - Wikipedia
网页Depolymerization (or depolymerisation) is the process of converting a polymer into a monomer or a mixture of monomers. [1] This process is driven by an increase in entropy. Depolymerization of polystyrene via radical elimination mechanism.
Depolymerisation: breaking it down to basic building blocks
网页‘Depolymerisation’ is one of the ways to chemically recycle plastic waste. In this process, sorted plastic waste is broken down into monomers (basic building blocks) to feed them back into the plastic production.

网页2021年1月30日 · This paper presents the critical situation of plastic pollution, various methods of plastic depolymerization based on different kinds of polymers defined in the Society of the Plastics Industry (SPI) Resin Identification Coding System, and the opportunities and challenges in the future.
网页In this review, we focus our interests on polymer depolymerisation through photochemical approach. A variety of light sources, including ultraviolet ( UV ) light, visible light, infrared ( IR ) and near infrared (NIR ) induced polymer depolymerisation s are described in two classes of polymers , natural and synthetic
Depolymerization within a Circular Plastics System
网页Among recycling technologies, chemical depolymerization offers a route to virgin quality recycled plastics, especially when valorizing complex waste streams poorly served by mechanical methods.
Organocatalysis for depolymerisation - ScienceDirect
网页Organocatalysts, which are promising “green” substitutes for traditional organometallic complexes, are able to catalyse depolymerisation reactions yielding highly pure small molecules that are adequate for subsequent polymerisations or other uses.
