    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: 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.
