Samenvatting
Abstract: Closed-loop recycling of polymers represents the key
technology to convert plastic waste in a sustainable fashion.
Efficient chemical recycling and upcycling strategies are thus
highly sought-after to establish a circular plastic economy. Here,
we present the selective chemical depolymerization of
polycarbonate by employing a vanillin derivative as bio-based
feedstock. The resulting di-vanillin carbonate monomer was used
in combination with various amines to construct a library of
reprocessable poly(imine-carbonate)s, which show tailor-made
thermal and mechanical properties. These novel poly(iminecarbonate)
s exhibit excellent recyclability under acidic and
energy-efficient conditions. This allows the recovery of monomers
in high yields and purity for immediate reuse, even when mixed
with various commodity plastics. This work provides exciting new
insights in the design of bio-based circular polymers produced by
upcycling of plastic waste with minimal environmental impact.
