Abstract: The invention comprises compounds, used for treating synthetic fibres &c. (see Division D1), of the formula <FORM:1011909/C3/1> where R1 is hydrogen, an alkyl radical of 1-4 carbon atoms or hydroxy alkyl of 2-4 carbon atoms, X denotes a radical of the formula -COR2 or -A3OCOR2, R2 is an alkyl radica of 10-20 carbon atoms, (A1-O) is an ethyleneoxy and/or propylene-oxy radical, A2 is an alkylene radical of 2-5 carbon atoms, A3 is an alkylene radical of 2-4 carbon atoms and n is 5-35.  The compounds may be prepared either (1) by cyanoethylating a polyalkylene glycol, hydrogenating, and reacting the resultant diamine with a long chain fatty acid or an amide-forming derivative of such an acid, or (2) by forming the dichloride of the polyalkylene glycol, reacting this with a primary alkylamine or a primary or secondary hydroxyalkylamine and acylating the resultant diamine with a long chain fatty acid or an ester- or amide-forming derivative of such an acid.  In examples: (A) acrylonitrile is added to polyethylene glycol (mol. wt. 810) and sodium methylate.  After neutralization the product is hydrogenated and heated with stearic acid. (B) Polyethylene glycol (mol. wt. 810) is reacted with thionyl chloride.  The dichloride obtained is stirred in monoethanolamine and anhydrous sodium carbonate, and the diamine formed is reacted with stearic acid. In further examples, stearic acid is reacted with o ,o 1-di-(aminopropyl)-octadecaethylene glycol ether and with o ,o 1-di-(aminopropyl)-tridecaethylene glycol ether. The treating agent may be used in aqueous solutions or dispersions which also contain dispersing, emulsifying or stabilizing agents, e.g. adducts of ethylene oxide with long chain alcohols, mercaptans, amines, carboxylic acids or esters or amides thereof, fatty alcohol sulphonates, alkylaryl sulphonates and partial esters of polybasic organic or inorganic acids and long chain alcohol or ether alcohols.ALSO:Textile materials of synthetic macromolecular substances are treated and given an antistatic finis by polyalkylene glycolamide of the formula <FORM:1011909/D1-D2/1> where R1 is hydrogen, an alkyl radical of 1-4 carbon atom or hydroxy alkyl of 2-4 carbon atoms X is a radical of the formula-COR2 or -A3-OCOR2 R2 is an alkyl radical having 10-20 carbon atoms (A (A1-O) is an ethyleneoxy and/or propyleneoxy radical, A2 is an alkylene radical having 2-5 carbon atoms, A3 is an alkylene radical haveing 2-4 carbon atoms, and n is 5-35.  The treating agent is applied in the form of an aqueous solution or dispersion, or as a solution in an organic liquid.  A dispersing, emulsifying or stabilising agent may also be present. Examples describe the treatment of polyester fibres, including dyed fibres and union cloth consisting of 45% wool and 55% polyester fibre, with, e.g. aqueous solutions of the reaction product of (1) stearic acid and w, w1-di-(aminopropyl)-octadeca-ethylent glycol either, (2) stearic acid and the reaction product of diethanl amine and the dichloride of a polyethylene glycol (mol wt 800).
