tion, be discussed nuder the heading of polymeric nonaqueous dispersions. However, t o those who work in the field and follow new developments, the term nonaqueous dispersions has acquired a distinct meaning t h a t circumscribes precisely the subject in question, independent of what the term might mean in the classical chemical sense. It is t o this specialized attribution of the title that this review will address itself. The common abbreviation NAD will be employed.
