Abstract

Patente de Invenção: <B>"NUCLEAçãO DE POLIAMIDAS NA PRESENçA DE HIPOFOSFITO"<D>. A presente invenção provê composições de poliamidas compreendendo uma poliamida, náilon 2,2 e um agente de branqueamento contendo fósforo tendo a fórmula (I), onde R é hidrogênio, um grupo alquila com 1 a 6, carbonos, um grupo cicloalquila com 5 a 6 carbonos, ou um grupo aromático fenila ou metilfenila, e M é hidrogênio ou um metal. Em uma forma de realização preferida, a poliamida é náilon 6,6 (poliexametileno adipamida) e o agente de branqueamento contendo fósforo é um ácido hipofosfórico ou um hipofosfito de metal. Prefere-se especialmente hipofosfito de sódio. As composições de poliamidas da presente invenção melhoraram os tempos de ciclos de moldagem e são tenazes, brancas e de coloração estável.Invention Patent: <B> "NUCLEATION OF POLYAMIDES IN THE PRESENCE OF HYPOPPHOSPHITE" <D>. The present invention provides polyamide compositions comprising a polyamide, nylon 2.2 and a phosphorus-containing bleach having formula (I), where R is hydrogen, an alkyl group with 1 to 6, carbons, a cycloalkyl group with 5 to 6 carbons, or a phenyl or methylphenyl aromatic group, and M is hydrogen or a metal. In a preferred embodiment, the polyamide is nylon 6.6 (polyiexamethylene adipamide) and the phosphorus-containing bleach is a hypophosphoric acid or a metal hypophosphite. Sodium hypophosphite is especially preferred. The polyamide compositions of the present invention have improved molding cycle times and are tenacious, white and stable in color.
