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.
Claims12
A method for manufacturing a stable compatibilized mixture of two or more immiscible organic compounds, the method consisting of steps (1) combining the two or more immiscible organic compounds with from about 10 to about 80 wt. % glycol derived from polymerization of alkylene oxide having from 2 to 4 carbon atoms and tetrahydrofuran, (2) heating the combination of step (1) at a temperature of from about 35° C. to about 65° C., and (3) recovering a compatibilized product mixture stable in the liquid phase at a temperature of from about 40° C. to about 200° C., said compatibilized product mixture consisting of the two or more immiscible organic compounds and the glycol derived from polymerization of alkylene oxide having from 2 to 4 carbon atoms and tetrahydrofuran.
