摘要

A new AB2 monomer, designed from a template of the repeating unit of the hyperbranched polyimides by nonideal A2+ B3 polymerization, was successfully prepared via a multistep synthesis. Hyperbranched polyimides, having the same repeating unit as that by nonideal A2+ B3 polymerization, were prepared from this new AB2 monomer by direct self- polycondensation in the presence of diphenyl (2, 3-dihydro-2-thioxo-3-benzoxazolyl) ...
