Polytetramethylene Ether Glycol Uses

Polytetramethylene ether glycol (PTMEG) is a homopolymer obtained by cationic ring-opening polymerization. PTMEG is a linear polyether glycol with primary hydroxyl groups. At room temperature, PTMEG is a white waxy solid. When the temperature exceeds room temperature, PTMEG is melted into a clear, colorless liquid. PTMEG is readily soluble in alcohols, esters, ketones, aromatic and chlorinated hydrocarbons and insoluble in aliphatic hydrocarbons and water.
