ABSTRACT:
The present invention provides a process to produce toughened nylon compositions by blending a masterbatch comprising from about 15 to about 120 parts by weight of an .alpha.-polyamide with 100 parts by weight of a functionalized hydrogenated conjugated diolefin polymer and then blending the masterbatch with a sufficient amount of .alpha.-polyamide to result in a total of from about 200 to about 2000 parts by weight of .alpha.-polyamide in the resultant composition to form a toughened nylon composition. The toughened nylon composition has a 1/8 inch notched Izod impact toughness of greater than 10 ft-lb/in at -20.degree. F. when 20 parts by weight of the functionalized hydrogenated polyisoprene is blended according to this invention with a total of 80 parts by weight of nylon 6.
