We have achieved major improvements in the efficient chemical recycling of waste fiber-reinforced plastics (FRPs). The effects
of reduction in the amounts of dimethylaminopyridine (DMAP) used for depolymerization were examined. The treatment of waste
FRP in the presence of 1 or 2 wt% DMAP resulted in the successful recovery of monomeric materials that could be employed in
the polymerization process to produce recycled plastic. The separation of linker units from glass fiber, however, was unsuccessful.
The purity of the recovered monomeric material, when treated with activated charcoal, was improved to about 70%. This resulted
in effective decoloration of the recovered monomer. Finally, the purified material, after undergoing repolymerization, provided
high-quality recycled plastic comparable to new plastics produced from new monomers. 相似文献
