ABSTRACT:
Block poly(trimethylene-ethylene ether) glycols are disclosed. The block poly(trimethylene-ethylene ether) glycols can be prepared by the polycondensation of 1,3-propanediol reactant and polyethylene glycol reactant. The block poly(trimethylene-ethylene ether) glycols can be 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.
