Title:
DEPOLYMERIZABLE COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2023/238559
Kind Code:
A1
Abstract:
A depolymerizable copolymer according to the present invention is obtained through copolymerization of two or three or more monomers that make up a depolymerizable homopolymer which decomposes into the monomers via heat, light, and the like. The depolymerizable homopolymer decomposes into the monomers via heat, light, and the like, and has an extremely high monomer recovery rate of 90% or greater; examples of the same include polymethyl methacrylate, poly α-methyl styrene, and polytetrafluoroethylene. The monomers that make up these homopolymers are methyl methacrylate (MMA), α-methyl styrene (AMS), and tetrafluoroethylene (TFE). Such copolymers have a depolymerization property wherein the polymers decompose into the monomers via heat and light, and reuse thereof is easy.
