SALT RESISTANT POLYAMIDES

摘要

Disclosed is a polyamide composition including at least one semi-aromatic copolyamide, said semi-aromatic copolyamide consisting essentially of about 25 to about 55 mole percent repeat units of the formula -C(O)(CH2)mC(O)NHCH2ArCH2NH- (I) and about 45 to about 75 mole percent repeat units of the formula -C(O)(CH2)mC(O)NH(CH2)nNH- (II) wherein m is 8, 10, and/or 12, n is 6, 10 and/or 12 and Ar is a meta-substituted benzene ring; and wherein said polyamide has a melting point equal to or less than 225 °C. Also disclosed are molded articles including the polyamide composition.
