Partially aliphatic, high molecular weight polyimide copolymers were successfully synthesized using an ester−acid high-temperature solution imidization route by which noncrystalline, soluble materials were obtained. Variations in the aliphatic content produced a series of polyimides having different glass transition temperatures and processing char...

High molecular weight, soluble, amorphous, partially aliphatic polyimides were successfully synthesized using an ester acid high-temperature solution imidization route, which allows one to control desired glass-transition (Tg) and processing temperatures. This method involves the prereaction of aromatic dianhydrides with ethanol and a tertiary amin...

The isomeric diamine monomer 5(6)-amino-1-(4-aminophenyl)-1,3,3-trimethylindane (DAPI) was successfully synthesized via the dimerization of α-methylstyrene followed by nitration and reduction. High molecular weight, soluble polyimides were synthesized via ester–acid solution imidization techniques and had glass-transition temperature values ranging...

Polyimide-polydimethylsiloxane block or segmented copolymers are reviewed with respect to synthesis, characterization, structure-property relationships and other special characteristics. The siloxane-modified imides have developed into important materials over the past 10 years. Although some thermal and thermooxidative stability is lost through in...
