Applications of Polyethylene Glycol Monomethallyl Ether
Polyethylene glycol monomethallyl ether can be used as a functional polyether intermediate in the synthesis of specialty polymers and modified polyether materials.
Its methallyl group provides a reactive site for polymer modification and the preparation of polyether-containing copolymers.
Unsaturated polyalkylene glycol ether monomers are also relevant to the development of polymer additives, including cement admixtures and dispersing materials. Suitability for a particular formulation depends on molecular weight, ethoxylation degree, and polymerization performance.
