<p>Liquid surfactant polymer products of tetrahydrofuran and ethylene oxide, and process for making the same, are provided herein. The polymers comprise a hydrophobic central segment, transition copolymer segments extending outwardly from the central segment characterized by a continuously increasing EO mer unit content relative to the THF mer units therein, and hydrophilic termini segments of substantially EO mer units.</p> |
