Method for producing polyamide nanocomposites

[Abstract] The present invention relates to a method for producing a polyamide nanocomposite comprising a base polymer containing an aromatic component and an organically modified phyllosilicate with a front feeder and a side feeder In a twin-screw extruder, the method being characterized in that 8 to 15% by weight of the base polymer pellets (A) are metered into a front feeder of a twin-screw extruder. The main part of the base polymer pellets (B) is fed through a side feeder of a twin screw extruder and 2-8 wt% organically modified phyllosilicate is metered into the base polymer pellets (A) Part of the melt, therefore, this weight % ratio relates to the final or finished polyamide nanocomposite. According to the present invention, the method can be used to produce packaging or packaging materials that have enhanced UV absorption and improved gas and aroma barrier effects. Furthermore, the invention also discloses corresponding packages, molded bodies and applications thereof produced by the method.

[Sovereign Items] 1. A method for producing polyamide nanocomposites consisting of a base polymer and an organically modified phyllosilicate in a twin-screw extruder with a front feeder and a side feeder. Medium manufacturing, characterized in that 8 to 15% by weight of base polymer pellets (A) are metered into the front feeder of a twin-screw extruder, the main part of which is the base polymer pellets. (B) 2-8 wt % organically modified phyllosilicate is metered into the melt of the base polymer pellet (A) portion through a side feeder feed of a twin screw extruder. Each formulation component was added to a total of 100% by weight.
