| titleOfInvention | Method for producing hydroxyl group-containing polyether, method for producing hydrolyzable silyl group-containing polyether, and method for producing urethane prepolymer |
| abstract | There is provided a method for producing a hydroxyl group-containing polyether capable of producing a hydroxyl group-containing polyether having a high molecular weight with a smaller molecular weight distribution. A cyclic ether compound is subjected to a ring-opening addition reaction with an initiator having at least one hydroxyl group per molecule in the presence of a double metal cyanide complex catalyst and the following plasticizer (Z), so that the weight average molecular weight is 5 A method for producing a hydroxyl group-containing polyether, comprising producing a hydroxyl group-containing polyether (I) having a molecular weight of 1,000 to 500,000. Plasticizer (Z): a compound having a hydroxyl value of 2.0 or less and a weight average molecular weight smaller than that of the hydroxyl group-containing polyether (I) to be produced, comprising phthalates, epoxy plasticizers, One or more compounds selected from the group consisting of polyester plasticizers, polyether plasticizers, polyvinyl polymers, aliphatic hydrocarbon compounds having 8 to 18 carbon atoms, and chlorinated paraffins having 10 to 30 carbon atoms.
