Reaction Steps
The reaction product was added by 184 g (2.95 mol) of ethylene glycol (EG), 85 g (0.8 mol) of diethylene glycol (DEG) and 30 g (0.2 mol) of phthalic anhydride (PA), and then esterified by heating to 200° C. with removing water distillated from the reaction product. When the acid value of the esterified product reached 22, it was cooled to 120° C. to obtain a dicyclopentadiene-modified unsaturated polyester (second step).
