摘要： A catalyst composition for use in the preparation of poly(butylene terephthalate) from dimethyl terephthalate, comprising: (a) a titanium compound primary catalyst, from about 0.0005 PHR to about 5 PHR; (b) a first co-catalyst containing at least one of Zn, Co, Mn, Mg, Ca, or Pb series compounds, between about 0.0001 PHR and 5 PHR; and (c) a second co-catalyst containing an alkali metal phosphate, an alkali metal phosphite, an alkali hypophosphite, or an alkali metal polyphosphate between about 0.0001 PHR and 5 PHR; wherein PHR represents parts of the primary catalyst or the co-catalyst per one hundred parts, by weight, of dimethyl terephthalate. Preferred titanium compounds include tetrabutyl titanate or tetra(isopropyl)titanate. Preferred metal compounds for use as first co-catalyst are metal acetates. The alkali metal phosphate can be a phosphate salt containing one, two, or three metal groups; and the alkali metal phosphite can be a phosphite salt containing one or two metal groups. The alkali metal hypophosphite can be a hypophosphite salt containing any number of alkali metal groups. The alkali metal polyphosphate can be a polyphosphate salt containing one, two, three, four, or five alkali metal groups. With this catalyst composition, the rate of polycondensation was increased by 40 percent or more. The catalyst composition is also effective in the preparation of poly(butylene terephthalate) from terephthalic acid.

摘要： 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.
