ABSTRACT:
The polyester-grafted polyamide of the present invention comprises a polyamide as the backbone and a thermoplastic polyester as the graft and has a number-average molecular weight in terms of standard polymethyl methacrylate of 50,000 to 500,000 as determined by gel permeation chromatography using 1,1,1,3,3,3-hexafluoro-2-propanol. The polyester-grafted polyamide is useful as a modifier for polyesters and polyamides.
