## Abstract We have synthesized a series of fully aliphatic polyimides (APIs) from bicyclo[2,2,2]octβ7βeneβ2,3,5,6βtetracarboxylic dianhydride (BOCA) and various aliphatic diamines, including linear aliphatic, flexible alicyclic, and rigid adamantyl diamines. We performed the polymerization reactio

Several new polyamides were synthesized by direct polycondensation of the 1,3-bis[4-(4-aminophenoxy)phenyl]adamantane ( I) with various dicarboxylic acids. The polyamides had inherent viscosities and number-average molecular weights ( M n ) of 0.46-0.96 dL/g and 28,000-109,000, respectively. All pol
## Introduction During the course of these studies, we have found that bis(4-aminophenyl) ether, a weakly basic aromatic diamine, together with tetrafunctional pyromel-Aromatic polyimides have been well-known since the litic acid, could form readily the salt monomer with 1 : early 1960s as the mos
We have studied the nonisothermal and isothermal crystallization kinetics of an aromatic thermotropic liquid crystalline polyimide synthesized from 1,2,4,5-benzenetetracarboxylic dianhydride (PMDA) and 1,3-bis[4-(4-aminophenoxy) cumyl] benzene (BACB) by means of differential scanning calorimetry (DS
