What is polyether?
Polyether, also known as polyethylene glycol ether, is a synthetic oil with the largest sales volume at present. It is a linear polymer prepared by ring opening homopolymerization or copolymerization with ethylene oxide, propylene oxide and epoxy butane as raw materials under the action of catalyst.
Polyether: polyether
Chinese Name: polyether
Melting point: 57-61 ℃
Boiling point: 200 ℃ (lit.)
Flash point: 230 ° f
Polyether Polyols (hereinafter referred to as polyether) are prepared by polymerization of initiator (compounds containing active hydrogen groups) with ethylene oxide (EO), propylene oxide (PO), epoxy butane (Bo) in the presence of catalyst.
The largest output of polyether is glycerol (glycerol) as initiator and epoxide (generally Po and EO are used together). Various general polyether polyols are produced by changing the feeding mode (mixed or separate), dosage ratio and feeding order of Po and EO. Polyether (polyether polyol) is an important derivative of propylene oxide and one of the main raw materials for the synthesis of polyurethane.
