Title:
METHOD FOR INCREASING FATIGUE RESISTANCE OF POLYAMIDES
Document Type and Number:
WIPO Patent Application WO/2014/076139
Kind Code:
A1
Abstract:
The invention pertains to a method for improving fatigue resistance of a polyamide [polyamide (A)] composition, said method comprising incorporating into the polyamide composition at least one additive comprising phenolic hydroxyl groups [groups (ArOH)] and/or aromatic sulfonic groups [groups (ArSO3X)] [additive (H)], wherein incorporation of said additive (H) causes a decrease in the melting point of the polyamide composition of no more than 13°C.
