Chemical recycling of unsaturated polyester resin and its composites via selective cleavage of the ester bond
An efficient strategy has been developed for chemical recycling of unsaturated polyester resin (UPR) and its glass fibre reinforced polymer composites (GFRP) by selectively cleaving C–O bonds using the AlCl 3 /CH 3 COOH system. AlCl 3 promotes acyl exchange reaction between CH 3 COOH and UPR. This p...
