Patent number: 10479863Abstract: A method for preparing a polyether polyol in a continuous reaction cycle is described. In the method, a low molecular-weight alcohol is polymerized with an alkylene oxide to obtain a low molecular-weight polymer. The low molecular-weight polymer is used as an initiator to react with the alkylene oxide and the low molecular-weight alcohol in the presence of a DMC catalyst and an acid promoter to obtain an intermediate-target polymer. A portion of the intermediate-target polymer is used for producing the target polymer, and the other portion is recycled for reproduction of the intermediate-target polymer. No initiator prepared with a base catalyst is used, and thus the loss of material and the discharge of residue and waste water are reduced. The DMC concentration is kept constant in the target polymer during the production such that the dewatering time and induction time are greatly reduced.Type: GrantFiled: March 30, 2016Date of Patent: November 19, 2019Assignee: HUAIAN BUD POLYURETHANE SCIENCE & TECHNOLOGY CO., LTDInventors: Weixin Qi, Bing Hu, Yong Han

Patent number: 9758619Abstract: Ethylene carbonate is polymerized by itself or together with another cyclic monomer such as 1,2-propylene oxide in the presence of a double metal cyanide catalyst. Most of the ethylene carbonate adds to the chain to form a terminal carbonate group, which decarboxylates to produce a hydroxyethyl group at the end of the polymer chain. The polymerization of more ethylene carbonate onto the chain end results in the formation of poly(ethyleneoxy) units. Therefore, the process provides a method for making poly(ethyleneoxy) polymers without the need to polymerize ethylene oxide. The process is useful for making polyethers that are useful as water-absorbable polymers, surfactants and as raw materials for polyurethanes. The process is also useful for increasing the primary hydroxyl content of a polyether.Type: GrantFiled: August 15, 2012Date of Patent: September 12, 2017Assignee: Dow Global Technologies LLCInventors: Esther E.
