CLASS: ICM: D06M013-38.Some commonly used reagents like 24938-64-5 is used in this experiment. ICS: C08J005-24. ICA: C08J005-12. APPLICATION: JP 84-143399 12 Jul 1984. PRIORITY: US 83-513437 13 Jul 1983. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Aramid fibers treated with I (R, R1, or R2 = H, carboxy, hydroxy, amino, vinyl) have good adhesion to the matrix resin. Thus, poly(p-phenyleneterephthalamide) [24938-64-5] fibers were treated with 4-carboxybenzenesulfonyl azide [17202-49-2], heat-treated 0.5 h at 140°, and heat-treated 0.5 h at 190°. The treated fibers were embedded in a compn. 24938-64-5 which is the cas registry number is also used here. contg. Epon 826 [25068-38-6] 100, 1,4-butanediol diglycidyl ether 25, and Tonox 30 parts and cured 1.5 h at 120° and 1 h at 175° to give a composite with interlaminar shear strength 9100 psi. ..
