    摘要： The invention relates to a method for the production of polyamide nanocomposites made from base polymers comprising aromatic components and organically-modified phyllosilicates in a double-screw extruder with a front-feeder and a side-feeder. Said method is characterised in that a portion (A) from 8 to 15 wt. % of a granulate of the base polymer is introduced in the front-feeder of the double-screw extruder and the main portion (B) of said granulate of the base polymer is introduced by means of the side feeder of the double-screw extruder and that 2 to 8 wt. % of the modified phyllosilicate is introduced into the melt of the granulate portion (A) of the base polymer, whereby the wt. % proportions relate to the finished polyamide nanocomposite. According to the invention, packaging materials with high UV absorption and improved gas and aroma barrier effect can be produced by said method. Furthermore, the corresponding packagings the use thereof and moulded bodies produced by means of said method are disclosed.

    摘要： A partially aromatic copolyamide is formed of: (a) 5 to 30 weight-% of hexamethylene diamine (b) 10 to 40 weight-% of metaxylylene diamine (c) 15 to 50 weight-% of adipic acid (d) 5 to 45 weight-% of at least one aliphatic dicarboxylic add with 7 to 10 carbon atoms, preferably sebacic acid and/or acelaic acid, wherein the components (a) to (d) add up to 100 weight-%, and the add groups and the amine groups are essentially present in equimolar portions. These novel copolyamides are used for producing barrier layers for mono- or multi-layered composites, such as foils or containers, infusion- or ostomy bags, shrink wraps for meat, fish and cheese packagings or sausage skins, wherein the copolyamides can be present in the pure form or as a mixture with other polymers, in particular in combination with further polymer layers.

    摘要： A method is disclosed for producing a polyamide molding compound which includes the following method steps: addition and dissolving of m-xylylene diamine and dicarboxylic acids, which include adipic acid and aromatic dicarboxylic acids, with water and additives in a dissolving chamber and production of a mixture, the sum of the aromatic dicarboxylic acids added being 2 mol-percent to 15 mol-percent (in relation to the addition of dicarboxylic acids); transfer of the mixture into a reaction vessel and polycondensation of the mixture in this reaction vessel; granulation of the polycondensate; drying of the granulate. This method is distinguished in that the polycondensation is performed at a pressure of at most 10 bar and a temperature of 255° C. to 270° C., the pressure being built up while heating the reaction vessel to 255° C. to 270° C. and—immediately after the mixture has reached the maximum temperature—being reduced to atmospheric conditions while maintaining a temperature of 255° C. to 270° C., and the polycondensation being continued at this temperature and a pressure of less than 800 millibar; and the granulate is subjected to an underwater crystallization before drying.
