DOI: 10.1007/s10562-016-1965-5
Abstract: Phosphotungstic acid (HPW) was added to mesoporous silica (MS) to form catalysts by two distinct methods, i.e., a direct-synthesis method and an impregnation method. The catalysts were evaluated in the synthesis of soybean oil-based polyols.… read more here.

DOI: 10.1016/j.polymdegradstab.2018.07.001
Abstract: Abstract To obtain a substitute for petroleum-based polyols and simultaneously solve the flammability problem of polyisocyanurate (PIR) foams, a novel phosphorus-containing soy-based polyol (PCSO) was firstly synthesized. Then, PCSO was used to fabricate biomass flame-retardant… read more here.

DOI: 10.1021/acssuschemeng.8b02423
Abstract: Two novel bio-based polyols were synthesized from cardanol via thiol-ene/thiol-epoxy dual click-reactions. Compared with the cardanol-based polyols synthesized by the thiol-ene reaction, the cardanol-based polyols synthesized by thiol-ene/thiol-epoxy dual reactions have a higher hydroxyl number… read more here.
