Allyl-terminated polyether
profile
These products contain the function of one or two double bonds and therefore have good reactivity. The EO chain is not just polyethylene glycol, but can also be a mixed copolymer of polyethylene glycol and polypropylene glycol, or just polypropylene glycol. Popular products are mainly polyethylene glycol or blended EO/PO copolymers.
Product ends can be terminated with methyl, allyl, butyl, epoxy or acetyl groups, so these products contain only a small amount of free hydroxyl groups, involvingAdverse reactions caused by the-OH group can be reduced or avoided.
Most of these products are used to react with siloxane, using platinum as a catalyst, and the double bonds of the polyether interact with siloxane.Addition reaction occurs on the Si-H bond to obtain polyether modified silicone.
