“…For example, phenylated dianhydrides cannot be used to prepare high molecular weight poly(amic acids). These sterically hindered monomers, however, react rapidly with diamines at elevated temperatures to give high molecular weight polyimides [20,100,101].…”

“…The thermoplastic PI result from the polyaddition of bismaleinimides and HZ-R-ZH compounds, where HZ may be diamine, disulfide dialdoxim, etc. Although aromatic PI retain usable properties at 300 • C for months and withstand exposures of a few minutes well over 500 • C, their applications have been limited [30]. Polyamide imide was introduced around 1976 and polyether imide around 1982 [2,5].…”

During the last century and a half, new families of engineering materials known as polymers have been discovered and produced, that have not only challenged the classical materials but have also made possible the realization of new products which have contributed to extend the range of activities of mankind. This paper is a brief review of the history of the most important groups of polymeric materials, such as plastics, fibers and elastomers. In the growth of polymeric materials during the last century and a half, plastics are the leader followed by fibers and elastomers.  Koninklijke Brill NV, Leiden, 2008

“…[1][2][3] Improvements in polyimide properties have been sought by incorporating trifluoromethyl or other perfluoroalkyl groups. Fluorinated polyimides are known to have low dielectric constants, 4,5 low water absorption, 5,6 high transparency, 7,8 and high solubility 9 compared to fluorine-free polyimides.…”

Aromatic polyetherimides were synthesized from a fluorine containing aromatic carboxylic acid dianhydride, 2,2-bis[4-(3,4-dicarboxyphenoxy)phenyl]-hexafluoropropane dianhydride (6F-BABPA) and five typical aromatic diamines including 1,1-bis(4-aminophenyl)-1-phenyl-2,2,2-trifluoroethane (3F-DAM) by two-step procedures-amidation to polyamic acids (PAA), followed by thermal imidization of PAA. The chemical and physical properties of the newly prepared polyetherimides (PEI) were compared in terms of their chemical structures, inherent viscosities, mechanical, and thermal properties. All polyetherimides were well soluble in common organic solvents such as N-methyl-2-pyrolidone (NMP), N,N-dimethylformamide (DMF), N,N-dimethylacetamide (DMAc), pyridine, and methylene chloride. A PEI prepared from 6F-BABPA/3F-DAM was especially easily dissolved in NMP. The glass transition temperature (T g ) range of the obtained PEI was 209 -257°C. The dielectric constants and refractive index were 2.8 -3.2 and 1.61-1.56, respectively. The polyetherimide, 6F-BABPA/BAPP, with a low fluorine content (11.4% fluorine content), has 0.99% water absorption, whereas the polyetherimide, 6F-BABPA/4-BDAP, having a high fluorine content (26.0% fluorine content) showed 0.35% of water absorption.
