Abstract: IT HAS BEEN SUGGESTED THAT THE UTILITY OF SYNTHETIC FIBERS OF POLYAMIDE COULD BE INCREASED BY DISPERSING IN THE POLYAMIDE A MINOR PROPORTION OF AN ANTISTATIC POLYETHER COMPOUND DERIVED FROM THE REACTION OF AN AMINE HAVING AT LEAST ONE PRIMARY GROUP WITH AT LEAST ONE ALKYLENE OXIDE HAVING 2 TO 4 CARBON ATOMS, E.G., A COMPOUND REPRESENTED BY THE FORMULA:

H-(O-CH2-CH2)Y-(O-CH(-CH3)-CH2)C-N(-(CH2-CH(-CH3)-O)D-

(CH2-CH2-O)Z-H)-CH2-CH2-N(-(CH2-CH(-CH3)-O)A-(CH2-CH2-O)

X-H)-(CH2-CH(-CH3)-O)B-(CH2-CH2-O)W-H

WHERE A,B,C,D,W,X,Y AND Z ARE EACH A WHOLE NUMBER AND THE TOTAL OF A,B,C AND D IS BETWEEN 8 AND 850 AND THE TOTAL OF W,X,Y, AND Z IS BETWEEN 8 ANF 1,000. HOWEVER, WITH INCORPORATION OF THIS ANTISTATIC ADDITIVE IN THE POLYAMIDE, SERIOUS PROBLEMS HAVE BEEN ENCOUNTERED IN MELT-SPINNING DUE TO THE FREQUENT OCCURRENCE OF "DRIPS" OF THE MOLTEN POLYMER AS IT EMERGES FROM THE SPINNERET. IT HAS NOW BEEN FOUND THAT THE OCCURENCE OF SAID DRIPS CAN BE ELMINATED OF GREATLY REDUCED BY REACTING TH ANTISTATIC POLYETHER ADDITIVE WITH A COMPOUND OF THE FORMULA:

(R-SO3)N-MENTAL

OR A COMPOUND OF THE FORMULA:

R-SO3-Z

WHEREIN R IS SELECTED FROM THE GROUP CONSISTING OF ALKYL, CYCLOALKYL, ARYL AND ARYLALKYL, N IS A WHOLE NUMBER CORRESPONDING TO THE VALENCE OF THE METAL, AND Z IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, AMMONIUM CATION AND SUBSTITUTED AMMONIUM CATION. MOREOVER, IT HAS BEEN FOUND THAT THE ANTISTATIC PROPERTIES AND DYEABILITY OF THE RESULTING POLYAMIDE FIBER ARE IMPROVED.

Abstract: 1. IN A PROCESS FOR THE FORMATION OF POLYCAPROAMIDDE FIBER FROM A FIBER-FORMING E-POLYCAPROAMIDE POLYMER HAVING EXCESS NUMBER OF CARBOXYL END GROUPS OVER AMINO END GROUPS, BY EXTRUDING THE MOLTEN POLYMER THROUGH AN ORIFICE INTO A QUENCHING MEDIUM AND THEREAFTER STRETCHING THE RESULTING FILAMENT, THE IMPROVEMENT WHEREIN SAID FIBER-FORMING E-POLYCAPROAMIDE POLYMER IS PREPARED BY A PROCESS COMPRISING: (A) CONTINUOUSLY FORMING A MOLTEN POLYMERIZATION REACTION MIXTURE AT 240*-290*C. FROM E-CAPROLACTAM; (B) CONTINUOUSLY SMOOTHLY STIRRING SAID REACTION MIXTURE WHILE FLOWING OVER THE SURFACE THEREOF A GAS CAPABLE OF REMOVING MOISTURE FROM SAID REACTION MIXTURE, AT A FLOW RATE OF AT LEAST 2 UNIT VOLUMES OF SAID GAS, MEASURED AT STANDARD TEMPERATURE AND PRESSURE, PER HOUR PER EACH UNIT VOLUME OF SAID REACTION MIXTURE, UNTIL THE TOTAL PRIMARY AMINO GROUP PLUS CARBOXYL GROUP ANALYSIS OF THE RESULTING POLYMER IS NOT ABOVE 135 MILLIEQUIVALENTS PER KILOGRAM OF POLYMER; AND THEN (C) CONTINUOUSLY REACTING SAID POLYMER AT 250-290*C. WITH ABOUT 0.1-0.7 MOL PER 100 MOLS OF LACTAM IN THE POLYMER, OF AN ESTER OF A DICARBOXYLIC ACID, HAVING THE FORMULA

R-OOC-R1-COO-R2

WHERE R IS A HYDROCARBON RADICAL HAVING BETWEEN 9 AND 16 CARBON ATOMS, R1 IS A HYDROCARBON RADICAL HAVING BETWEEN 4 AND 18 CARBON ATOMS, AND R2 IS HYDROGEN OR A HYDROCARBON RADICAL HAVING BETWEEN 9 AND 16 CARBON ATOMS, UNTIL THE PRIMARY AMINO GROUP ANALYSIS OF THE POLYMER IS NOT ABOVE 34 MILLIEQUIVALENTS PER KILOGRAM OF POLYMER AND THE CARBOXYL GROUP ANALYSIS OF THE POLYMER IS BETWEEN ABOUT 50 AND ABOUT 90 MILLIEQUIVALENTS PER KILOGRAM OF POLYMER, THEREBY REDUCING THE OCCURENCE OF NUBS IN THE FIBER.

Abstract: POLYESTERS HAVING LITTLE OR NO DISCOLORATION ARE PREPARED BY CONDENSING DIGLYCOL:TEREPHTHALATE ESTER INTERMEDIATES INCLUDING THE MODIFIED ESTERS AND ISOMERS THEREOF IN THE PERSENCE OF 0.005 TO 0.40 PERCENT ANTIMONY OXALATE BASED ON THE TEREPHTHALATE CONTENT OF THE POLYMER EMPLOYED. THE PROCESS OF THIS INVENION PROVIDES A MEANS FOR OBTAINING COLORLESS FILM AND FIBER-FORMING SYNTHETIC, LINEAR POLYESTERS HAVING IMPROVED PROPERTIES.
