Abstract
The invention relates to impact modifiers for polyamide compositions which improve the impact strength of the polyamides without adversely affecting the flexural modules of the composition. The impact modifiers comprise blends of general purpose rubbers and a halogenated copolymer of a C.sub.4 to C.sub.7 isomonoolefin and an alkylstyrene. In addition, the invention is drawn to a polyamide composition containing such impact modifiers.
