T 4770 A B S T R A C T PROCESS TO BLEND POLYAMIDES AND FUNCTIONALIZED ELASTOMERS AND BLENDS PREPARED BY THIS METHOD The present invention provides a process to produce toughened nylon compositions by blending a masterbatch comprising from 15 to 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 -polyamide to result in a total of from 200 to 2000 parts by weight of -polyamide in the resultant composition to form a toughened nylon composition. The toughened nylon composition has a 3.2 mm (1/8 inch) notched Izod impact toughness of greater than 534 J/m (10 ft-lb/in) at -29 °C (-20 °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.
