Patent ID: 6887930

Claim:
A polyamide composition, comprising: 50 to 90 parts by weight of (A) one or more semiaromatic polyamides having dicarboxylic acid units containing 60 to 100 mole % of terephthalic acid units and diamine units containing a total of 60 to 100 mole % of 1,9-nonanediamine units and/or 2-methyl-1,8-octanediamine units; and wherein the amount by weight of (A) is based on 100 parts by weight of both (A) and (B); and 50 to 10 parts by weight of (B) one or more aliphatic polyamides selected from the group consisting of a polyamide L and polyamide MN; wherein the polyamide L repeating unit is represented by wherein X is an alkylene unit; and the polyamide MN repeating unit is represented by wherein Y and Z are alkylene units and are the same or different; in which the total number of carbon atoms of the polyamide L repeating unit and one half of the total number of carbon atoms of the polyamide MN repeating unit is 7 to 12; and wherein the amount by weight of (B) is based on 100 parts by weight of both (A) and (b).
