Microwave-Assisted Degradation of Unsaturated Polyester Resin into HDPE-Modified Aerogels for Oil Adsorption and Oil/Water Separation
Thermosetting unsaturated polyester resin (UPR) is difficult to reprocess because curing generates an irreversible three-dimensional network. Here, cured UPR was treated in a microwave-assisted hydrazine hydrate/NaOH medium at 70 °C for 30 min to produce a water-swellable UPR-derived product (NUPR). NUPR was combined w...
