Abstract

The kinetic and structuring features of the solid phase polymerization of 1,4-bis-( m-acetylaminophenyl) butadiyne as well as the optical and photoelectrical properties of the polymer have been studied. A strong retardation of the thermal polymerization of this monomer and an appreciable decrease in the rate of radiation-induced polymerization were found which is connected with breakdown of the monomer crystal lattice. The photoconductivity spectra of crystalline polymer samples with various degrees of conversion are represented by curves which rise monotonically in the direction of the short wavelengths, over a wide range (900-300 nm) and do not replicate the absorption spectra. This may be because the absorption of crystalline samples in the 530–680 nm range is due to excitation of photoelectrically inactive exciton states whilst the formation of carriers occurs as a result of a shorter wave transition of zone-zone valency conductivity of the polymer chain.
