| titleOfInvention | The preparation method of the polyether polyol with high activity containing ester bond in main chain |
| abstract | The invention belongs to polyhydric alcohol technical field, and in particular to the preparation method of the polyether polyol with high activity containing ester bond in a kind of main chain.Described preparation method is that Oleic acid and terminal hydroxy group material are carried out esterification in the presence of a catalyst, and the product that esterification is obtained carries out polyreaction in the presence of auxiliary agent with expoxy propane, the polyether polyol with high activity containing ester bond is obtained after process.Polyhydric alcohol prepared by the present invention contains more ehter bond, so as to ensure which as the activity of raw material, being capable of room temperature foaming.Due to containing ester bond in the main chain of product of the present invention, so as to there is good intermiscibility with foaming agent and auxiliary agent, can store for a long time, it is excellent as the pliability of foamed product obtained in raw material.Even if the pliability of foamed product is not interfered with yet as foaming agent using water. |
