ABSTRACT:
This invention concerns the preparation of stabilized polydimethylsiloxane-polyalkylene glycol block copolymers complexed with alkyl phenols. The resultant complexes have improved storage stability and are soluble in mineral oils. Solutions of the complexes in mineral oil exhibit better foam-inhibition than do oil dispersions of the uncomplexed polymers. In addition the oil-soluble complexes have improved extreme pressure properties.
