End capped Allyl Polyether
Description
These end capped allyl polyether contain one or two functional groups (double bond). The end product by methyl, allyl, epoxy group, butyl or acetyl termination.The glycol chain not necessarily only consists of polyethylene glycol. It is also possible to make random ethylene and propylene glycol copolymers or polymers based only on polypropylene glycol. Popular products are based on pure ethylene glycols and random EO/PO copolymers.
For most applications, these products are reacted with siloxanes to obtain the so called polyether modified siloxanes (silicones). This hydrosilylation reaction is a Pt (platinum) catalyzed reaction. The double bond of the polyether is reacted with the Si-H bond of the siloxane.Our reactive glycol diethers do not contain any free hydroxyl groups. Therefore, undesirable side reactions involving the -OH group are avoided.
