Abstract
We prepared amphiphilic alternating copoly(amide acid)s (PAAs) from rel[1R,5S,6R]-3-oxabicyclo [3.2.1]octane-2,4-dione-6-spiro-3′- (tetrahydrofuran-2′,5′-dione)(DAn), 2,4-diaminobenzenesulfonic acid and nonsulfonated diamines in one pot based on unique regioselectivity in the ring opening reaction of DAn. The aggregation behavior of PAAs in aqueous solution were studied using transmission electron microscopy and dynamic light-scattering measurements. In general, spherical aggregates were observed. We also observed the difference in the aggregation behavior between alternating and random copolymers.
