Room temperature soluble melt-condensed polyamide interpolymers
Abstract
Abstract MELT-CONDENSED POLYAMIDE INTERPOLYMERS CONSISTING ESSENTIALLY OF AT LEAST FOUR DIFFERENT RECURING POLYAMIDE REPEAT UNITS IN WHICH (A) ABOUT 35 PERCENT OF THE AMIDE EQUIVALENTS ARE POLYMETHYLENE-$-AMINOACID REPEAT UNITS OF 6 TO 20 CARBON ATOMS, (B) ABOUT 10 TO 30 PERCENT 5 OF THE AMIDE EQUIVALENTS ARE DIAMINE DIACID REPEAT UNITS IN WHICH HE DIAMINE IS POLYMETHYLENE DIAMINE OF 6 TO 20 CARBON ATOMS AND THE DIACID IS POLYMETHYLENE DIACID OF 6 TO 20 CARBON ATOMS, (C) ABOUT 10 TO 30 PERCENT OF THE AMIDE EQUIVALENTS ARE DIAMINE DIACID REPEAT UNITS IN WHICH THE DIAMINE IS POLYMETHYLENE DIAMINE OF 6 TO 20 CARBON ATOMS AND THE DIACID IS POLYMETHYLENE DIACID OF 6 TO 20 CARBON ATOMS DIFFERENT FROM THE DIACID OF (B) ABOVE, AND (D) ABOUT 10 TO 30 PERCENT OF THE AMIDE EQUIVALENTS ARE DIAMINE DIACID REPEAT UNITS IN WHICH THE DIAMINE IS POLYMETHYLENE DIAMINE OF 6 TO 20 CARBON AND THE DIACID IS POLYMETHYLENE DIACID OF 6 TO 20 CARBON ATOMS DIFFERENT FROM THE DIACIDS OF (B) AND (C) ABOVE, OR DIMERIZED FATTY ACID OF 16 TO 48 CARBON ATOMS, ARE SOLUBLE TO THE EXTENT OF AT LEAST ABOUT 20 PERCENT IN COMMON SOLVENTS AT ROOM TEMPERATURE.
