    Abstract: 1485737 Copolymers of tetrahydrofuran BASF AG 15 Jan 1975 [16 Jan 1974] 1698/75 Heading C3R [Also in Division D1] Polyalkylene oxide adducts have the general formula R-X where R is the radical after removal of oxygen linked active hydrogen atoms of a C 8-22 alcohol or carboxylic acid or an oxyalkylation product thereof with 1-20 moles of ethylene oxide and/or propylene oxide; X is the radical of a copolymer of ethylene oxide and/or propylene oxide and tetrahydrofuran. The total amount of alkylene oxide units in R-X is 60-95% by wt. and the molar ratio of units derived from ethylene oxide and/or propylene oxide to units derived from tetrahydrofuran is 1 : 0À5 to 1 : 3. Typical examples are derived from oleic acid : ethylene oxide: tetrahydrofuran in weight ratios 1 : (1À5-2À5): (1À5-3). Uses.-Emulsifiers in the pigment dyeing of textiles.
