Definitions

  • the present invention relates to the field of molded and extruded thermoplastic articles having improved long-term high temperature aging characteristics.
  • High temperature resins based on polyamides possess desirable chemical resistance, processability and heat resistance. This makes them particularly well suited for demanding high performance applications including automotive and electrical/electronics applications.
  • the mechanical properties generally tend to decrease due to the thermo-oxidation of the polymer. This phenomenon is called heat aging.
  • heat stabilizers also referred as antioxidants
  • examples of such heat stabilizers include hindered phenol antioxidants, amine antioxidants and phosphorus-based antioxidants.
  • heat stabilizers include hindered phenol antioxidants, amine antioxidants and phosphorus-based antioxidants.
  • polyamide compositions three types of heat stabilizers are conventionally used to retain the mechanical properties of the composition upon exposure to high temperatures.
  • phenolic antioxidants optionally combined with a phosphorus based synergist as previously mentioned

  • Another problem is the heat ageing performance of polyamide compositions that generally have low levels of reinforcing agents or none at all. Since unreinforced compositions are generally used in applications that require some flexibility; an important attribute of unreinforced thermoplastics is the retention of strain at break upon heat ageing.

  • (meth)acrylate is meant to include acrylate esters and methacrylate esters.
  • the polyamide resin used in the present invention has a melting point and/or glass transition.
