  • Patent number: 6812324
    Abstract: A method for preparing nylon 6 copolymer containing 5-sulfoisophthalate salts comonomer. The method includes the steps of reacting 5-sulfoisophthalate salts ester with aliphatic diamine in a molar ratio of 2˜20 at 160˜200° C., followed by completely removing the unreacted aliphatic diamine, to obtain the intermediate compound with terminal amine, 5-sulfobenzenediamide compound (formula III). Next, caprolactam and aliphatic diacid (formula IV) are reacted at 200˜260° C. to form an oligomer with a low molecular weight. 5-Sulfobenzenediamide (formula III) and catalyst are then added into the oligomer obtained in previous step to cause a polymerization reaction at 200˜280° C. to obtain nylon 6 copolymer containing 5-sulfoisophthalate salt comonomer. The molar ratio of E/C is 0.005˜0.150 and the molar ratio of D/E is 1.05-1.00. Compounds present in the water extract are greatly reduced.
