Antistatic composition and fiber made therefrom

Abstract

Abstract 1. AN ANTISTATIC COMPOSITION OF MATTER COMPRISING A HIGH MOLECULAR WEIGHT FIBER-FORMING POLYCARBONAMIDE WHEREIN THE RECURRING CARBONAMIDE LINKAGES ARE AN INTEGRAL PART OF THE POLYMER CHAIN, SAID POLYCARBONAMIDE BEING EITHER A COPOLYMER OF AT LEAST TWO DIFFERENT POLYCARBONAMIDE-FORMING SUBSTANCES OR A MELT BLEND OF AT LEAST TWO DIFFERENT POLYCARBONAMIDE POLYMERS, SAID POLYCARBONAMIDE BEING COMPOSED OF ABOUT 6-24 WEIGHT PERCENT AROMATIC NUCLEI AND A HIGH MOLECULAR WEIGHT POLY(ALKYLENE ETHER) AS A DISTINCT PHASE IN THE FORM OF SMAALL ELONGGATED PARRTICLES FROM 1 TO 15 PERCENT BASED ON THE WEIGHT OF THE COMPOSITION FORMED BY THE ESTER INTERCHANGE REACTION OF R-OOC-Y-COO-R WHEREIN R IS AN ALKYL RADICAL OF 1 TO 4 CARBON ATOMS AND Y IS A DIVALENT ORGANIC RADICAL SELECTED FROM THE GROUP CONSISTING OF -(PHENYLENE)-, -(NAPHTHALYENE)- AND A LINEAR OR BRANCHED ALKYLENE RADICAL OF 1 TO 20 CARBON ATOMS; AND (HO-(A-O)N-R''(-R")(-X))2-N-R''-(O-A)N-OH WHEREIN R'' IS A LINEAR OR BRANCHED C2-C4 ALKYLENE RADICAL, R" IS A C12-C24 ALKYL RADICAL, A IS A LINEAR OR BRANCHED C2-C4 ALKYLENE RADICAL, THE SUM OF THE N''S IS ABOUT 25 TO 7575, X IS HYDROGEN OR AN ALKYL RADICAL OF 1 TO 4 CARBON ATOMS; AND THE MOL RATIO OF (A) TO (B) IS FROM ABOUT 1:9 TO ABOUT 1:1.
