Definitions
- the invention relates to a transparent molding compound made from a copolyamide, which is suitable for producing transparent, printable articles.
- the utility model DE 295 19 867 Ul describes a decorable film made from a copolyamide which is composed of the monomer units laurolactam and caprolactam and / or hexamethylenediamine / dicarboxylic acid.
- Copolyamides of this type are generally transparent and, owing to their low crystallinity, are also easy to decorate by screen printing, but problems repeatedly arise in the production of films from such copolyamides by extrusion.
- the films crystallize very slowly and only at low temperatures, so that a long cooling section is necessary or only low extrusion speeds are possible.
- the slow crystallization also causes the film to warp and shrink. When printing on such films by means of screen printing, they easily become brittle due to stress cracking.
- Part of the task was to develop transparent, partially crystalline copolyamide compositions for articles such as molded parts and foils that have a rapid crystallization. Another part of the task was to produce such articles from transparent, partially crystalline copolyamide compositions which have no warpage and do not shrink.
- DE 199 37 117 A1 discloses a film with a layer of a copolyamide with nanoscale nucleating particles dispersed therein; the copolyamide contains building blocks which are derived from aromatic monomers; the rest of the building blocks are based on PA6 or PA6 / 66.
- the nucleation reduces the post-shrinkage of the film.
- the script also shows that the film can be printed; the methods used to do this are not specified. This film is used as food packaging.
- a polyamide molding compound should be made available which can be processed into articles such as molded parts or foils which can be easily printed by means of screen printing. This requires a low crystallinity of the polyamide so that the colorant can be anchored in the surface of the article to be decorated by dissolving the polyamide.
- a molding composition which contains the following components: a) a partially crystalline copolyamide as indicated below and b) an effective amount of a crystallization aid which is selected from

- Suitable dicarboxylic acids of component ⁇ ) also have 4 to 40 C atoms; Examples include adipic acid, 2.2.4- or 2.4.4-trimethyladipic acid, azelaic acid, sebacic acid, 1.12-dodecanedioic acid, cyclohexane-1,4-dicarboxylic acid, 4.4 '-dicarboxydicyclohexylmethane, S.S'-DimethyM ⁇ ' - dicarboxydicyclohexylmethane, 4.4'- Dicarboxydicyclohexylpropane and 1,4-bis (carboxymethyl) cyclohexane. Mixtures of different dicarboxylic acids can also be used. Suitable other lactams or corresponding co-aminocarboxylic acids are those with 6, 7, 8, 9, 10, 11 or 12 carbon atoms.
- the copolyamide used has a certain crystallinity, so that a minimum degree of stress crack resistance is guaranteed.

- Polymer nanocomposites made from organophilized phyllosilicates and polymers were first described in US Pat. No. 2,531,396. The organophilization of layered silicates is also known, for example, from US Pat. Nos. 2,531,472, 2,996,506, 4,105,578, 4,412,018, 4,434,075, 4,434,076, 4,450,095 and 4,874,728.
- EP-A-0 358 415 describes the production of polymeric nanocomposites by polymerizing lactams in the presence of pretreated layered silicates. This improves the barrier properties against gases, heat resistance and rigidity.
- Quantities of 0.001 to 2% by weight, particularly preferably 0.01 to 1.5% by weight and particularly preferably 0.1 to 1% by weight of the nanoscale fillers are preferably introduced into the copolyamide matrix, as a result of polycondensation can be accomplished in the presence of the filler or by subsequent compounding.

- Suitable metal salts, metal oxides and metal hydroxides react with the end groups of the copolyamide, the resulting neutralized end groups having a nucleating effect. It is advantageous if the copolyamide has an excess of carboxyl end groups. Alkali or alkaline earth metal carbonates or hydrogen carbonates can be used particularly advantageously. The reaction produces water and carbon dioxide, which can be easily removed from the copolyamide melt.
- the metal salts oxides or hydroxides, preferably 0.01 to 5% by weight, particularly preferably 0.1 to 4% by weight and particularly preferably 0.5 to 3% by weight, based on the copolyamide, used.

- Corresponding compounds of heavy metals can of course also be used, e.g. B. zinc carbonate.
- B. zinc carbonate e.g. B. zinc carbonate.
