Diese Additive sind für transparente Polyamide und Copolyamide ungeeignet, da sie die Transparenz negativ beeinflussen. Außerdem ändern sich auch die mechanischen und physikalischen Eigenschaften der Polyamide bei steigenden Additivmengen in unvorteilhafter Weise. Schwerentflammbare halogenfreie Formteile mit VO-Einstufung nach UL-94 Spezifikation der Underwriter Labora tories, USA sind ganz besonders für die Elektro- und Elektronik-Industrie von Interesse. Dabei ist die Transparenz solcher Formteile eine wichtige Eigen schaft. Die EP-OLS 0 242 732 schützt Mischungen aus semikristallinen und amorphen Polyamiden mit aromatischen, gesundheitlich nicht unbedenklichen Polyphosphonaten als flammhemmende Additive, ohne jedoch trotz hoher Additiv-Mengen den für die industrielle Anwendung unerläßlichen VO-Wert für 0,8 mm dicke Prüfkörper zu erreichen.These additives are unsuitable for transparent polyamides and copolyamides, because they negatively affect transparency. They also change mechanical and physical properties of polyamides with increasing Additive amounts disadvantageously. Flame retardant halogen free Molded parts with VO classification according to UL-94 specification of the Underwriter Labora tories, USA are very special for the electrical and electronics industry from Interest. The transparency of such molded parts is an important feature shaft. EP-OLS 0 242 732 protects mixtures of semi-crystalline and amorphous polyamides with aromatic, not harmless to health Polyphosphonates as flame retardant additives, but without high ones Additive quantities the VO value for which is indispensable for industrial application To achieve 0.8 mm thick test specimens.
In der DE-AS 26 60 075 wird als flammhemmendes Additiv eine Tetraacetyl diamin-Verbindung, wahlweise in Kombination mit halogenhaltigen Produkten, vorgeschlagen. Diese Additive sind für die Transparenz von Polyamiden nicht geeignet.DE-AS 26 60 075 uses a tetraacetyl as a flame-retardant additive diamine compound, optionally in combination with halogen-containing products, suggested. These additives are not for the transparency of polyamides suitable.
In der US PS 37 89 091 und der US PS 38 49 368 werden ringförmige Phos phonsäureester als flammhemmende Additive für verschiedene Homopolyme re, darunter auch PA66 beansprucht ohne daß deren Lehre zur Lösung der speziellen Problematik transparenter Copolyamide und insbesondere solcher mit VO-Qualifikation führt. In the US PS 37 89 091 and US PS 38 49 368 ring-shaped Phos phonic acid esters as flame retardant additives for various homopolymers re, including PA66 claimed without their teaching to solve the special problems of transparent copolyamides and especially those leads with VO qualification.
