Abstract
For the purpose of obtaining high polymers possessing high thermal stabilities and superior mechanical properties, high molecular weight polymers of general formula,
have been prepared by melt-polymerization of p-bis (phenylaminodimethylsilyl) benzene with various organic diols. The polymers were soluble in organic solvents such as benzene, tetrahydrofuran, and chloroform and possessed film-and fiber-forming properties. Thermogravimetric analyses of the polymers showed that the thermal degradation did not occur at temperatures below 400°C, exhibiting excellent thermal stabilities of the polymers. However, alkali-and water-resistance properties of the polymers were inferior to the polymers consisting siloxane linkage in the main chain. The dielectric permittivities of the polymer containing biphenyl group, and of its charge-transfer complexes with TCNQ and chloranil were measured at room temperature. The increase of dielectric permittivities by complexation was very small.
