  • Polyether-ester amide and permanently antistatic resin composition
    Patent number: 5096995
    Abstract: A transparent polyester-ester amide having a permanently antistatic property is obtained by copolymerizing (a) an aminocarboxylic acid, a lactam, or a salt derived from a diamine and a dicarboxylic acid; (b) a diol of the formula: ##STR1## wherein R.sup.1 and R.sup.2 are an ethylene oxide or propylene oxide group, Y is covalent bond, alkylene, alkylidene, cycloalkylidene, arylalkylidene, O, SO, SO.sub.2, CO, S, CF.sub.2, C(CF.sub.3).sub.2 or NH, X is H, alkyl, halogen, sulfonic acid or salt thereof, l is 0 or an integer of 1-4, and m and n an integer of 1-15; (c) a poly(alkylene oxide)glycol or a diol of the formula:HO--R.sup.3 --OH (IV)wherein R.sup.3 is alkylene, alkylidene, cycloalkylidene or arylalkylidene; and (d) a dicarboxylic acid; wherein the content of the polyether-ester units is 10 to 90 wt. %.
