Filled and unfilled polyamide compositions of improved toughness comprise a polyamide component comprising recurring aliphatic terephthalamide units and a modifying component comprising a functionalized block copolymer comprising styrene polymer blocks and rubber blocks comprising ethylene/propylene, ethylene/butylene, or ethylene/pentylene polymer blocks or a combination thereof.

Polyphthalamide composition

Impact-modified polyphthalamide resins are improved in ductility and rigidity when blended with polypropylene and a carboxylated polyolefin resin. The blends exhibit an excellent balance of ductility and rigidity.

Polyphthalamide blends

Filled and unfilled polyamide compositions of improved toughness comprise a blend of a polyamide comprising recurring aliphatic terephthalamide units, a functionalized polyolefin and a functionalized block copolymer comprising styrene polymer blocks and rubber blocks comprising ethylene/propylene ethylene/butylene or ethylene/pentylene polymer blocks or a combination thereof.
