Poly[dimethylsiloxane-co-methyl(3-hydroxypropyl)siloxane]-graft-poly(ethylene glycol) methyl ether
Poly[dimethylsiloxane-co-methyl(3-hydroxypropyl)siloxane]-graft-poly(ethylene glycol) methyl ether (CAS: 68938-54-5) is a versatile silicone-based copolymer. It exhibits amphiphilic properties due to the combination of a hydrophobic siloxane backbone and a hydrophilic polyethylene glycol (PEG) side chain. This unique structure allows it to function effectively as a surfactant, emulsifier, and dispersant across various chemical and materials science applications, including microfluidics and bioelectronics.
