Abstract:
A poly(trimethylene-ethylene ether) glycol is disclosed. The poly(trimethylene-ethylene ether) glycol is, preferably, prepared by the polycondensation of 1,3-propanediol reactant and ethylene glycol reactant. The composition is preferably used in breathable membranes, synthetic lubricants, hydraulic fluids, cutting oils, motor oils, surfactants, spin-finishes, water-borne coatings, laminates, adhesives, packaging, films and foams, fibers and fabrics.
