Abstract (en)
[origin: WO2011094542A2] 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 (I) : -C(O)(CH2)mC(O)NHCH2ArCH2NH-, and about 45 to about 75 mole percent repeat units of the formula (II) : -C(O)(CH2)mC(O)NH(CH2)nNH-, wherein m is 8, 10, and/or 12, n is 6, 10 and/or 12 and Ar is a meta-substituted benzene ring; and said polyamide has a melting point equal to or less than 225 °C; and 0.1 to 15 weight percent of one or more polyhydric alcohols having more than two hydroxyl groups and having a number average molecular weight (Mn) of less than 2000. Also disclosed are molded or extruded articles including the polyamide composition.
