Abstract: WHEN POLYAMIDES HAVING A SUBSTANTIAL PROPORTION OF PRIMARY AMINO END-GROUPS AND CARBOXYL END-GROUPS BOUND TO TERMINATING AGENTS CONTAINING TERTIARY OR UNREACTIVE SECONDARY AMINO GROUPS ARE MELT-BLENDED WITH POLYESTERS, FILAMENTS CAN BE SPUN THEREFROM WITHOUT ADVERSE INTERACTION BETWEEN THE POLYMERS AND WITH ENHANCED DYEABILITY.

Abstract: A NOVEL AMIDE HAVING THE GENERAL FORMULA:

BIS((CH3-R-CO-NH-(CH2)X-)2-N-CO-(CH2)N-)BENZENE

WHEREIN THE HEXAGON REPRESENTS THE BENZENE NUCLEUS, R IS A DIVALENT RADICAL CONTAINING UP TO BOUT 30 CARBON ATOMS WHICH CAN BE LINEAR OR BRANCHES ALIPHATIC, N IS AN INTEGER FROM 0 TO ABOUT 6, X IS AN INTEGER FROM 2 TO ABOUT 6, AND THE

-CO-(CH2)N-

RADICALS CONNECTED TO THE BENZENE NUCLEUS ARE RELATIVELY DISPOSED IN THE ORTHO, META, OR PARA POSITIONS. THE NOVEL AMIDE IS PREPARED FROM A NOVEL DIACYL DERIVATIVE OF A TRIAZA ALKANE HAVING THE GENERAL FORMULA:

CH3-R-CO-NH-(CH2)X-NH-(CH2)X-NH-CO-R-CH3

WHEREIN R IS A DIVALENT RADICAL CONTAINING UP TO ABOUT 30 CARBON ATOMS WHICH CAN BE LINEAR OR BRANCHED ALIPHATIC AND X IS AN INTEGER FROM 2 TO ABOUT 6. THESE COMPOUNDS ARE USEFUL IN INCREASING THE SOIL RESISTANCE OF SYNTHETIC FIBERS.
