These properties can be explained by the high bonding strength between sp.-hybridized carbon atoms and the special microstructure with parallel arrangement of polyaromatic sheets, however, without any crystallographic order i

When the substituent is chloro, methyl, .-butyl, or 1,1-dimethylhexyl, the polyterephthalate homopolyesters still melt at too high a temperature to be injection-molded or melt spun without thermal degradation, but additional modification with a flexible aliphatic component, a kinked ri

P. Bøgh Andersen,Claus B. Madsen,Erik Granumtemperatures ranging from ~150°C to ~300°C. Their outstanding thermo-oxidative stability and flame and solvent resistance are characteristic of aromatic polyimides but, unlike many other polyimides, they can also be processed by conventional techniques (e.g., injection molding). The key reactions in

The chemistry of the “doping” of polymers to the conductive state is discussed in terms of redox reactions and redox equilibria. The structure of oxidized poly(acetylene) is discussed based on available X-ray data and in an

Some of the key results obtained from a detailed study of polyimides carried out within IBM are summarized along with efforts aimed at optimizing the polyamic acid precursor to achieve improved processibility. Finally, some preliminary results of work on a new typ
