Claim 1

A SURFACE ACTIVE MIXTURE OF CONJAGATED POLYOXYALKYLENE COMPOUNDS CONTAININIG IN THEIR STRUCTURE OXYPROPYLENE GROUPS, OXYETHYLENE GROUPS AND THE NUCLEUS OF A REACTIVE HYDROGEN COMPOUND HAVING FROM 2 TO ABOUT 6 REACTIVE HYDROGEN COMPOUND HAVING UP TO AND INCLUDING 6 CARBON ATOMS PER MOLECULE AND BEING A MEMBER SELECTED FROM THE GROUP CONSISTING OF ALIPHATIC POLYHYDRIC ALCOHOLS, ALKYLAMINES, ALKYLENE POLYAMINES, CYCLIC AMINES, AMIDES AND POLYCARBOXYLIC ACIDS, SAID COMPOUNDS BING CHARACTERIZED BY HAVING HETERIC POLYMERIC CHAINS OF OXYPROPYLENE AND OXYETHYLENE GROUPS ATTACHED AT ONE OF THEIR ENDS TO SAID NUCLEUS OF THE REACTIVE HYDROGEN COMPOUND AT THE SITES OF ITS REACTIVE HYDROGEN ATOMS AND BY HAVING CHAINS OF OXYETHYLENE GROUPS ATTACHED TO THE OTHER ENDS OF SAID HETERIC CHAINS, SAID HETERIC POLYOXYPROPYLENE-POLYOXYETHYLENE CHAINS HAVING FROM 5-40 WEIGHT PERCENT OF OXYETHYLENE GROUPS, BASED ON THE WEIGHT OF SAID HETERIC CHAINS, AND HAVING AN AVERAGE MOLECULAR WEIGHT OF AT LEAST ABOUT 1000 AND UP TO ABOUT 25,000 AND THE OXYETHYLENE GROUPS IN SAID OXYETHYLENE CHAINS BEING SUFFICIENT IN WEIGHT SO AS TO CONTITUTE FROM ABOUT 5-90 WEIGHT PERCENT OF THE MIXTURE OF SURFACE ACTIVE COMPOUNDS.
