POLYOL COMPOSITION |
| 摘要 |
The present invention provides a polyol composition including a polyol having a polyester chain, wherein the polyol composition substantially contains no metal-base polymerization catalyst and an amount of phosphorus element derived from a polymerization catalyst is 1 to 1000 ppm. Furthermore, a method for producing a polyol composition is provided, including reacting a compound having an active hydrogen with a compound having at least one selected from the group consisting of carboxyl group, ester group and acid halide group in the presence of 0.0001-0.05 parts by mol of a phosphorus compound with respect to 1 part by mol of the active hydrogen without using a metal-based polymerization catalyst. |

1. A method for producing a polyol composition, comprising
reacting a compound having an active hydrogen with a compound having at least one selected from the group consisting of a carboxyl group, ester group and acid halide group in the presence of 0.0001-0.05 parts by mol of a phosphorus compound with respect to 1 part by mol of the active hydrogen without using a metal-based polymerization catalyst. |
