PURPOSE:To provide a compsn. mainly composed of a metal sulfide and a high-molecular compd., which can be used as a semiconductor, a power element for a solar cell, a commutating element, etc., by removing a solvent from a liquid material obtd. by dissolving a high-molecular material in a dispersion of a metal sulfide in a solvent in a state of a sol. CONSTITUTION:A sulfur compd. [e.g. H2S or (NH4)2S] is added to a soln. of a metal compd. [e.g. CdI2 or Cd(OCOCH3)2] in a solvent to prepare a liquid material contg. the metal sulfide in a state of a sol. A high-molecular material is dissolved in the liquid material to obtain a liquid material (apparently uniform soln.). The solvent is then removed from said liquid material by precipitation or evaporation to form the above compsn. Preferred solvents are compds. of the formula (wherein R, R' is H, alkyl). Preferred examples of the high- molecular compds. are those contg. a cyano, carbonyl or arom. group.
