Novel rigid semi-alicyclic dianhydride with large side groups for high performance colorless polyimides (CPIs)
A new dianhydride 9,10-diphenyl-9,10-bis(trifluoromethyl)-9,10-dihydroanthracene-2,3,6,7-tetraacid dianhydride (6FDPDA) with rigid semi-alicyclic structure was reported. CPI materials were prepared by copolymerizing 6FDPDA with 3,3′,4,4′-biphenyl tetracarboxylic dianhydride (BPDA) or 4,4’-(hexafluor...
