Antistatic fiber containing high molecular weight tris(b-hydroxyalkyl)-iso-cyanurate-alkylene oxide adducts
Abstract
Abstract IT HAS BEEN FOUND THAT AN ANTISTATIC FIBER OF POLYAMIDE OR POLYESTER CAN BE PREPARED BY UNIFORMLY DISPERSING IN THE POLYMER BETWEEN ABOUT 1 PERCENT AND ABOUT 10 PERCENT OF A COMPOUND REPRESENTED BY THE FORMULA H-(O-CH(-R'')-CH2-)R-O-CH(-R)-CH2-(2,6-DI(O=),5-(H-(O-CH (-R)-CH2-)T-O-CH(-R)-CH2-)-HEXAHYDRO-S-TRIAZIN-1,3-YLENE)- CH2-CH(-R)-O-(CH2-CH(-R)-O-)S-H WHEREIN R AND R'' ARE INDEPENDENTLY AT EACH OCCURRENCE HYDROGEN, METHYL OR ETHYL AND R, S, AND T ARE INTEGERS FROM 31 TO ABOUT 200. PREFERABLY, THE COMPOUND IS A BLOCK COMPOLYMER OF ETHYLENE OXIDE, PROPYLENE OXIDE AND TRIS(B-HYDROXYETHYL)ISOCYANURATE HAVING A MOLEUCLAR WEIGHT GREATER THAN 9,000, WITH THE ETHYLENE OXIDE MOIETY MAKING UP TO 10 TO 95 PERCENT OF THE MOLECULAR WEIGHT OF THE COMPOUND.
