CLASS: IC: C08L067-00; C08K005-35. APPLICATION: JP 82-167497 28 Sep 1982. DOCUMENT TYPE: Patent CA Section: 40 (Textiles) Polyesters resistant to d.p. lowering during melt spinning contains 0. 22102-60-9 is the cas registry number of certain chemical which is used as reagents here.1-10% 31 compd(s). selected from I, II, and III (R-R7 = H, monovalent org. group; R8, R9 = monovalent org. group; Z, Z' = divalent org. group; A = quadrivalent arom. group; X = divalent org. group to make the rings in II 5 or 6 membered; n, m = 0, 1). Thus, poly(ethylene terephthalate) (intrinsic viscosity 0.60) contg. 0.8 phr 2,2'-p-phenylenebis(2-oxazoline) [7426-75-7] was melt-spun at 285° and drawn to obtain a 150 denier/48 filament yarn with intrinsic viscosity 0.62 and tenacity 4.6 g/denier. .

DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Acrylic fibers with improved dimensional stability, esp. after washing at high temps., are manufd. by spinning a soln. of an acrylonitrile polymer contg. >20 mequiv CO2H group per kg polymer and a polyoxazoline in a polar org. solvent (1:1 molar ratio of CO2H to oxazoline groups in the soln.) and crosslinking by drying the fiber at 140-90° during the aftertreatment. Thus, a clarified soln. of 15 parts acrylic acid-acrylonitrile copolymer [25214-69-1] (555 mequiv CO2H/kg polymer) and 0.899 part 1,4-bis(2-oxazolin-2-yl)benzene [7426-75-7] in DMF was dry spun ad dried for 10 min at 165° during the aftertreatment. No change in fiber d. was obsd. after immersion in boiling water for 15 min. The fibers also showed improved tensile strength and decreased % elongation at break in comparison with com. 25214-69-1 is the cas registry number. This chemical is also mentioned in this article. acrylic fibers after washing at 90°. ..
