ABSTRACT:
Oxyalkylated cyclic phenol-aldehyde resins for example oxyalkylated cyclic tetramers; processes by which they are prepared; and method of using said oxyalkylated resins for a wide variety of uses, particularly as demulsifiers for water-in-oil type emulsions. Although oxyalkylated products are preferred, analogous products can also be prepared from alkylene sulfides, alkylene imines, or mixtures of more than one of these alkylene oxides, sulfides, or imines.
