Abstract
PURPOSE: To facilitate the production of a polycarbonate excellent in cracking resistance, impact resistance, heat resistance, etc., by reacting a dihydroxydiaryl compound with an N,N'-carbonyl bond-containing compound with the aid of an ester interchange catalyst.
CONSTITUTION: A dihydroxydiaryl compound (e.g., 4,4'-dihydroxy-diphenyl-1,1'- ethane) is reacted with an N,N'-carbonyl bond-containing compound (e.g., N,N'- carbonyldipyrrole) with the aid of an ester interchange catalyst (e.g., Na, Mg, ZnO).
