Abstract

Polyethylene glycol is formed by the interaction of ethylene oxide with water, ethylene glycol or ethylene glycol oligomers. Acidic or basic catalysts are used as catalysts in this reaction. Ethylene glycol and its oligomers are preferable as a starting material instead of water because it allows the creation of polymers with a low polydispersity. Polyethylene glycol has many desirable applications like an anti-dusting agent in agricultural formations, dye carrier in paints and ink and mold release agent, etc. Molecular interaction studies of PEG in various solvents are reported by many researchers. It is proposed to determine the activation energy and the molecular interaction properties of Polyethylene Glycol (PEG 400 and PEG 1500) in water for various concentrations ranging from 1 to 5 % at different temperatures from 303 to 318 K in steps of 5 K from the knowledge of relative viscosity which can be determined using a suitable viscometer.
