PURPOSE: A suspension catalyst for epoxy ring-opening polymerization is provided to have excellent catalytic activity in case epoxy ring-opening polymerization, and to reduce reaction time due to short polymerization induction period. CONSTITUTION: A suspension catalyst for epoxy ring-opening polymerization comprises a metal complex compound selected from a group consisting of double metal cyanate, multiple metal cyanate, and catalyst slurry comprising inorganic complex of C1-10 aliphatic alcohol dispersed into a polyether polyol dispersant. The organic complex is tert-butyl alcohol. The comprised amount of the organic complex is 0.1-20 parts by weight based on 1 parts by weight of metal complex. The weight average molecular weight of the polyether polyol dispersant is 400-2,00 Dalton. |
