2. Instruction
DMC catalyst (Double Metal Cyanide Catalyst) is a highly active catalyst used for epoxide
polymerization. Nowadays, it is considered as an ideal substitute to base catalyst (KOH). The
high-performance, low-monol polyether polyols are prepared with DMC catalyst and have the
properties of low viscosity, and narrow molecular weight distribution relatively with high
molecular weight.
Moreover, this catalyst can be used with less quantity (30g/mt) and reaction time is reduced
significantly.
