Priscius, inventor of Dolmaud/Ames, A; ·M·Suter Application (Patent) No. 03806950.4 Date of Application 2003.01.30 Certification Date Approval Notice No. 1643039 Audit Notice Date 2005.07.20 Instruction CD No. D0529 Main Classification No. C08J3/20 Classification No. C08J3/20; C08J3/22; C08K3 /34;C08K7/00;C08K9/04;C08L77/00 division Original application number Priority item 2002.1.30 CH PCT/CH02/00052 Abstract The present invention relates to a method for producing a polyamide nanocomposite, which consists of A base polymer containing an aromatic component and an organically modified phyllosilicate are produced in a twin-screw extruder with a front feeder and a side feeder, the method being characterized by: 8 to 15 wt. % of base polymer pellet (A) is metered into the front feeder of the twin screw extruder, and the main part of the base polymer pellet (B) is fed through the side of the twin screw extruder. Feeder, 2-8 wt% The mechanically modified phyllosilicate is metered into the melt of the (A) portion of the base polymer pellets, and therefore this weight percent 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. Sovereignty Item 1. A method of producing a polyamide nanocomposite made from a base polymer and an organically modified phyllosilicate in a twin-screw extruder with a front feeder and a side feeder , characterized in that 8 to 15% by weight of the base polymer pellets (A) are metered into the front feeder of the twin-screw extruder, the main part of the base polymer pellets (B ) 2-8 wt% organically modified phyllosilicate is metered into the melt of the base polymer pellet (A) part through a side feeder feed of a twin-screw extruder. The formulation components are added up to a total of 100% by weight.
