This invention provides a polytrimethylene terephthalate (PTT) composition which is inhibited from generating acrolein, a harmful substance, upon thermal oxidation and is less apt to deteriorate in color tone; and a process for producing the composition. The PTT composition comprises: PTT; and a compound having a phenolic hydroxy group (a) and a compound having a secondary amine structure (b), or a compound having both of a phenolic hydroxy group (a) and a secondary amine structure (b), and/or a modification of the compound(s). |
