A study of crystallization, melting, and morphology is carried out for homopolyimides derived from 3,3‘,4,4‘-biphenyltetracarboxylic dianhydride (BPDA) and either 1,3-bis(4-aminophenoxy)benzene (134APB) or 1,12-dodecanediamine (C12), as well as c

Crystalline homopolyimides are shown to occur by DSC from 3,3',4,4'-biphenyltetracarboxylic dianhydride (BPDA) and either 1,3-bis(4-aminophenoxy)benzene (134APB) or 1,12-dodecanediamine (C12). Additionally, copolyimides synthesized from these monomer

Imide ring formation upon heat treatment of diacylated diamines and dianhydrides was shown to be highly efficient. Evidence to support this conclusion was obtained from thermal gravimetric analyses, differential scanning calorimetry and infra-red spe

C. C. Walker[1] first demonstrated that size exclusion chromatography (SEC) is an effective analytical technique for observing molecular weight distribution changes (MWD) of polyamic-acids with time. The specific polyamic-acid studied was that based
