Abstract
Abstract Polycarbonamide suitable for melt spinning into multifilament fusion-free antistatic yarn having dispersed therein a polyalkoxylated triglyceride of a saturated fatty acid and an alkylene bis-alkyl carboxamide. The fusion-free multifilament yarn therefrom has enhanced properties and is particularly useful as a textile yarn.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
81 words
A POLYCARBONAMIDE COMPOSITION SUITABLE FOR MELT SPINNING INTO MULTIFIAMENT FUSION-FREE ANTISTATIC YARN, CONSISTING ESSENTIALLY OF A POLYCARBONAMIDE HAVING DISPERSED THEREIN, BASED ON THE WEIGHT OF POLYCARBONAMIDE, A. 1 TO 20 PERCENT OF A POLYALKOXYLATED TRIGLYCERIDE OF A SATURATED FATTY ACID WHEREIN THE POLYALKOXY PORTION THEREOF HAS A MOLECULAR WEIGHT RANGING FROM ABOUT 2,200 TO ABOUT 22,000 AND WHEREIN THE SATURATED FATTY ACID HAS 10 TO 30 CARBON ATOMS, AND B. 0.3 TO 2.0 PERCENT OF AN ALKYLENE BIS-ALKYLCARBOXAMIDE OF THE FORMULA
Claim 2
Dependent Claim
81 words
A POLYCARBONAMIDE COMPOSITION SUITABLE FOR MELT SPINNING INTO MULTIFIAMENT FUSION-FREE ANTISTATIC YARN, CONSISTING ESSENTIALLY OF A POLYCARBONAMIDE HAVING DISPERSED THEREIN, BASED ON THE WEIGHT OF POLYCARBONAMIDE, A. 1 TO 20 PERCENT OF A POLYALKOXYLATED TRIGLYCERIDE OF A SATURATED FATTY ACID WHEREIN THE POLYALKOXY PORTION THEREOF HAS A MOLECULAR WEIGHT RANGING FROM ABOUT 2,200 TO ABOUT 22,000 AND WHEREIN THE SATURATED FATTY ACID HAS 10 TO 30 CARBON ATOMS, AND B. 0.3 TO 2.0 PERCENT OF AN ALKYLENE BIS-ALKYLCARBOXAMIDE OF THE FORMULA
