Abstract

PURPOSE: To economically obtain the titled polymer suitable as a raw material for polyurethanes having excellent heat and hydrolytic resistance with hardly any coloring, by reacting a dialkyl carbonate, etc., treated with an adsorbent with a polyhydroxy compound.
CONSTITUTION: (A) A dialkyl carbonate, diaryl carbonate or alkylene carbonate is passed through a cylinder filled with (B) an adsorbent (e.g. activated clay) thereon and purified. (C) A polyhydroxy compound (e.g. 1,3-propanediol) is then added to carry out ester interchange reaction. Furthermore, reaction is then conducted at, e.g. 150W280°C under ≤20mmHg pressure, to afford the aimed polycarbonate.
