Reaction Steps
Adipic acid (702 g, 4.8 mol), trimethylolpropane (537 g, 4 mol), 2.4 g of Fascat® and 200 g of toluene were heated to 125–130° C. under nitrogen and water formed was separated off using a water separator. After a reaction time of 11 hours, the toluene was distilled off under reduced pressure. The viscous, hyperbranched polyester was soluble in butyl acetate or THF but insoluble in water.
