A HYDROPHILE SYNTHETIC PRODUCT WHICH IS THE ESTER OF (A) A POLYCARBOXY ACID SELECTED FROM THE GROUP CONSISTING OF ACYCLIC AND ISOCYCLIC DICARBOXY AND TRICARBOXY ACIDS, COMPOSED OF CARBON, HYDROGEN AND OXYGEN AND HAVING NOT MORE THAN 8 CARBON ATOMS AND (B) A HIGH MOLAL OXYPROPYLATED MONOMERIC ACYLIC TRIAMINO COMPOUND, WITH THE PROVISO THAT THE MONOMERIC TRIAMINO COMPOUND BE FREE FROM ANY RADICAL HAVING AT LEAST 8 UNINTERRUPTED CARBON ATOMS AND BE COMPOSED OF ELEMENTS SELECTED FROM THE GROUP CONSISTING OF CARBON, HYDROGEN, OXYGEN AND NITROGEN, THAT IT HAVE A MOLECULAR WEIGHT OF NOT OVER 800 AND AT LEAST A PLURALITY OF REACTIVE HYDROGEN ATOMS, THAT THE OXYPROPYLATED MONOMERIC TRIAMINO COMPOUND BE WITHIN THE MOLECULAR WEIGHT RANGE OF 2,500 TO 30,000 ON AN AVERAGE STATISTICAL BASIS, THAT THE RATIO OF PROPYLENE OXIDE PER REACTIVE HYDROGEN ATOM OF THE MONOMERIC TRIAMINO COMPOUND BE WITHIN THE RANGE OF 7 TO 70, THAT THE MONOMERIC TRIAMINO COMPOUND NOT REPRESENT MORE THAN 20% BY WEIGHT OF THE OXYPROPYLATED MONOMERIC TRIAMINO COMPOUND ON A STATISTICAL BASIS, THAT THE PRECEDING PROVISOS ARE BASED ON THE ASSUMPTION OF COMPLETE REACTION INVOLVING THE PROPYLENE OXIDE AND THE MONOMERIC TRIAMINO COMPOUND, THAT THE NITROGEN ATOMS BE LINKED BY ETHYLENE GROUPS AND THAT THE RATIO OF (A) TO (B) BE ONE MOLE OF (A) FOR EACH REACTIVE HYDROGEN ATOM PRESENT IN (B).
