Tpa-zro<inf>2</inf>-sio<inf>2</inf>-catalyzed polyesterification of tmp polyester
A series of tungstophosphoric acid (TPA)-ZrO 2 -SiO 2 particles (30 wt% TPA) with various ZrO 2 contents were prepared by sol-gel method. Using heptanoic acid (HA) as an end-capping agent, trimethylolpropane (TMP) polyester plasticizers were prepared by the TPA-ZrO 2 -SiO 2 -catalyzed polyesterifi...
