<p>High impact resistant polyamide resins containing a polyamide matrix comprising at least one amorphous polyamide dispersed particles of a toughener formed of a blend of ethylene, propylene, diene monomer rubber containing grafted succinic anhydride groups and an ionomer derived from ethylene, an alkyl acrylate and acrylic acid or methacrylic acid. The toughener has a particle size of less than about 360 nm, as determined by a small angle x-ray scattering technique. The toughener is present in the resin in the amount of at least 15% by weight.</p> |
