The polycondensation of polymerizable diamines bearing two generations of Percec-type dendritic blocks with dianhydrides led to the formation of novel aromatic polyamic acids that then were converted into a series of novel aromatic polyimides jacked with dendritic fragments. Their solubility in orga
