摘要: A composition comprising Polytrimethylene terephthalate (PTT) with a reduced emission of acrolein is obtained by contacting Polytrimethylene terephthalate (PTT) resin with an effective amount of a melt unstable, organic nitrogen-containing stabilizing compound. Such PTT resin has an acrolein formation rate at 280° C of less than 15 ppm/minute. Preferably the residual acrolein content of the PTT resin is less than 5 ppm. Preferred additive compounds include amines, amino acids, amidines, urea and other N-compounds. The additive compounds are added to the polymer in molten state and/or to the resin, which is then processed to fibers, filaments, non-wovens, films and/or mouldings.

摘要翻译: 通过使聚对苯二甲酸丙二醇酯(PTT)树脂与有效量的熔融不稳定的有机含氮稳定化合物接触,获得包含聚对苯二甲酸丙二醇酯(PTT)并具有降低的丙烯醛排放的组合物。 这种PTT树脂在280℃下具有小于15ppm /分钟的丙烯醛形成速率。 优选PTT树脂的残余丙烯醛含量小于5ppm。 优选的添加剂化合物包括胺,氨基酸,脒,尿素和其他N-化合物。 将添加剂化合物以熔融状态和/或树脂添加到聚合物中,然后将其加工成纤维,细丝,无纺布,薄膜和/或模制品。

摘要: A composition comprising Polytrimethylene terephthalate (PTT) with a reduced emission of acrolein is obtained by contacting Polytrimethylene terephthalate (PTT) resin with an effective amount of a melt stable, organic stabilizing compound. Such PTT resin has an acrolein formation rate at 280 °C of less than 15 ppm/minute. Preferably the residual acrolein content of the PTT resin is less than 10 ppm. The additive organic stabilizing compounds are free from nitrogen atoms. Preferred additive compounds include polyfunctional alkohols, alcoholates, aromatic carboxylic acid anhydrides, carboxylic acids and salts of carboxylic acids. The additive compounds are added to the polymer in molten state and/or to the resin, which is then processed to fibers, filaments, non-wovens, films and/or mouldings.
