Abstract:Recycling polymers by site-specific scission into short-chain
oligomers/polymers,
followed by recoupling these to form the original polymer presents
an energetically more favorable shorter-loop chemical recycling in
comparison to recycling into monomers. Here, we present the synthesis
and polymerization of tri-aromatic diesters to prepare polyesters
with acylhydrazone units as weak structural links. Two diester monomers
were prepared by combining methyl 5-chloromethyl-2-furoate, obtainable
from 5-chloromethylf… Show more
