Poly(ethylene glycol) butyl ether
Poly(ethylene glycol) butyl ether (CAS: 9004-77-7) is a hydroxy-functional polymer with the linear formula CH3(CH2)3(OCH2CH2)nOH. It presents as a liquid with an average molecular weight of approximately 206 g/mol. This versatile chemical finds utility as an intermediate in the synthesis of various materials and serves as a non-ionic surfactant. Its properties make it suitable for applications within materials science and polymer chemistry.
Non-ionic Surfactant
Poly(ethylene glycol) butyl ether acts as a non-ionic surfactant, reducing surface tension between liquids or between a liquid and a solid. This property is valuable in formulations requiring emulsification or wetting.
Chemical Intermediate
The hydroxyl end group allows this polymer to serve as a reactive intermediate in organic synthesis. It can be further functionalised for creating more complex molecules or polymers.
Materials Science
As a component in polymer science, it can be incorporated into polymer backbones or used as an additive to modify material properties such as flexibility or solubility.
