| titleOfInvention | Preparation of Polyols by Ring-opening Polymerization of Epoxy Monomers Using a Double Metal Cyanide Catalyst or a Multimetal Cyanide Catalyst Synthesized Using a New Organic Complexing Agent |
| abstract | The present invention relates to a highly active double metal cyan salt (DMC) catalyst or a multi-metal cyan salt (MMC) catalyst, and more particularly, to a double metal cyan salt (DMC) using a lactate-based compound as a complexing agent. A catalyst or a multimetal cyanide salt (MMC) catalyst and a polyol manufacturing process using the same. The catalyst according to the present invention uses a lactate-based compound as a complexing agent as a metal cyanate salt (DMC) catalyst or a multimetal cyanide salt (MMC) catalyst, and optionally uses a polyether compound as a complexing agent. do. The catalyst according to the present invention is simpler to produce than the catalyst using tert-butyl alcohol (t-butyl alcohol) as a complexing agent, the amount of the organic complexing agent is less, and environmentally friendly. In addition, when the ring-opening polymerization of the epoxy monomer using this catalyst, the polymerization activation is very fast, so the induction time or induction period is short and the activity is very high. In addition, the prepared polyol has a low viscosity, excellent transparency, significantly high molecular weight, narrow molecular weight distribution, and unsaturation level or monool content. |
