Abstract
The present invention relates to a novel method for compatibilizing, i.e. improving miscibility of, otherwise immiscible organic materials highly useful in the fibers industry, as well as the compatibilized product of the method. These compatibilized products are stable in the liquid phase at temperatures ranging from about 40° C. to about 200° C. The method involves use of a glycol derived from polymerization of alkylene oxide and tetrahydrofuran, the alkylene oxide having from 2 to 4 carbon atoms, i.e. poly(tetramethylene-co-alkyleneether) glycol, in the mixture.
Claims7
A stable compatibilized mixture consisting of two or more immiscible organic compounds and from about 10 to about 80 wt. % glycol derived from polymerization of alkylene oxide having from 2 to 4 carbon atoms and tetrahydrofuran, said stable compatibilized mixture being stable in the liquid phase at a temperature of from about 40° C. to about 200° C., wherein said immiscible organic compounds consist of a first organic compound selected from the group consisting of short chain glycols, polyethers and mixtures thereof, and a second organic compound selected from the group consisting of long chain polyols, polyesters and mixtures thereof.
