PEO-b-PTMEG

Polyethylene oxide (PEO),also known as polyethylene oxide,is a kind of crystalline,thermoplastic water-soluble polymer.It can form complexes with many organic low molecular compounds,polymers and some inorganic electrolytes. Properties:white vinegar solid,when the temperature exceeds room temperature,it will become transparent liquid.It is soluble in alcohols,esters,ketones,aromatic hydrocarbons and chlorinated hydrocarbons,but insoluble in aliphatic hydrocarbons and water.When the molecular weight increases,the solubility decreases.At room temperature,PTMEG has water absorption.Its water absorption depends on its molecular weight,and it can absorb 2% water at the highest.
