Two new monomers were prepared of the formula 3,X-bis(4-aminophenoxy)benzenemethanol (where X = 5, 3a; X = 4, 3b) and each copolymerized with 2,2-bis(4-aminophenyl)hexafluoropropane, 6-FDA, and 6 mol % of phthalic anhydride as an end-cap to afford polyimides 4 and 5, respectively. The CH2OH group in the polymers could be modified with excess 1,6-hexanediisocyanate to afford 100% modification of polymer 6 concomitant with formation of a pendent and reactive isocyanate group. This latter polymer… CONTINUE READING
