To modify the properties of polyamide 6 (PA6), trimethylolpropane tris[poly(propylene glycol), amine terminated] ether (PEA) was added to PA6 matrix by melt-mixing. By FTIR, 1H-NMR, DSC, melt index, relative viscosityand mechanical properties measurements, it was found that PA6/PEA blends have excellent melt-flowability, good thermal stability, high strength and good color. The melt flowability of PA6 can be significantly improved by a low loading of PEA without the loss of mechanical strengths.
