Claims
- 1. A filled polyamide composition consisting of:(a) from about 99 to about 92 wt %, based on resin components (a) and (b), of a polyphthalamide consisting of recurring units represented by the formula: wherein the mole ratio of A:B:C units lies in range 100-50:0-35:0-50, and wherein R comprises at least one divalent aliphatic radical having from 4 to 14 carbon atoms; (b) from about 1 to about 8 wt % based on resin components (a) and (b) of a pendant succinic anhydride-functionalized block copolymer comprising polymerized styrene blocks and rubber blocks comprising ethylene/propylene, ethylene/butylene or ethylene/pentylene polymer blocks or a combination thereof; (c) from about 10 to about 60 wt %, based on total composition, of at least one filler selected from particulate filler and structural fiber; and (d) from 0 to 200 pbw, per hundred parts combined weight of components (a) and (b), of at least one additional component selected from the group consisting of pigments, colorants, stabilizing additives, and lubricants.
- 2. The polyamide composition of claim 1 wherein the functionalized block copolymer comprises about 5 to about 50 weight percent polymerized styrene.
- 3. The polyamide composition of claim 1 wherein the functionalized block copolymer comprises about 0.5 to about 5 weight percent pendant succinic anhydride groups.
- 4. The polyamide composition of claim 1 wherein the functionalized block copolymer comprises a succinic anhydride-modified, hydrogenated block copolymer of styrene and 1,3-butadiene.
- 5. The polyamide composition of claim 1 wherein the functionalized block copolymer comprises a succinic anhydride-modified, hydrogenated block copolymer of styrene and isoprene.
- 6. A molded article comprising the filled polyamide composition of claim 1.
- 7. A blend consisting of the polyamide composition of claim 1 and at least one polyalphaolefin selected from the group consisting of polyethylene, polypropylene, poly-1-butene and poly4-methyl-1-pentene.
