Abstract:
A thermal stable composition comprising at least one polymer and at least one plasticizer, whereina. the polymer is semi-crystalline and exhibits a processing temperature equal to or greater than 220Â° C. and is polyamide-6, polyamide-6,6, polyamide-4,6, polyamide-6,9, polyamide-6,10, polyamide-6,12, polyamide-11 or polyamide-12; b. the plasticizer is an aromatic benzenesulphonamide, wherein the aromatic benzenesulphonamide is N-(2-hydroxyethyl)benzenesulphonamide, N-(3-hydroxypropyl)benzenesulphonamide, or N-(2-acetoxyethyl)benzenesulphonamide; and c. the plasticizer is incorporated into the polymer by mixing in the molten state in an amount of 2% to 30% by weight with respect to the total weight of the composition.
