Versuchsvorschrift
Nadic anhydride (164.2 g, 1.00 mole) and DCPD (66.1 g, 0.50 mole) were heated to 200° C. under nitrogen and held for 4 hours to obtain a DCPD-nadic anhydride. Maleic acid (93.0 g, 0.8 mole) was added at 110° C. and hold at 110-130° C. for 2 hours to obtained a clear liquid anhydride. The obtained anhydride (100 g) was mixed with epoxy resin (100 g, EEW 190), benzyltriethylammonium chloride (1.5 g) at 80° C. and degas with vacuum, the liquid resin was poured into a glass mold and heated at 80° C. for 4 hours, at 120° C. for 4 hours and at 150° C. for 2 hours to obtained a clear anhydride cured epoxy panel with a Tg of 135° C. tested by DSC.
