Abstract
New bis(ether phthalic anhydride)s were synthesized from hindered biphenylols, such as 2,2',3,3',5,5'-hexaphenyl-1,1'-biphenyl-4,4'-diol or 3,3',5,5'-teraphenyl-1,1'-biphenyl-4,4'-diol, and poly(ether imide)s have been prepared from them by solution condensation polymerization in NMP with o- or p-phenylenediamines. The T g 's of the poly(ether imide)s are increased by introduction of the rigid biphenyl moieties and they are soluble in common organic solvents. The polymers have 5% weight loss temperatures above 500°C
