Abstract

<B>"ESTRUTURA MULTICAMADA E TUBO OU CONDUTO"<D> A presente invenção trata de uma estrutura multicamada à base de poliamidas, apropriada em particular para a fabricação de tubos ou condutos destinados a transportar fluidos líquidos como álcoois, carburantes líquidos, carburantes que podem conter compostos oxigenados como, por exemplo, álcoois ou fluidos refrigerantes. A presente invenção propõe uma estrutura multicamada que compreende pelo menos uma camada interna e pelo menos uma camada externa superpostas. Segundo a presente invenção, pelo menos a camada interna é formada a partir de uma composição que compreende pelo menos uma poliamida termoplástica e pelo menos um agente modificador da resistência aos choques presente em uma concentração ponderal compreendida entre 10 e 50 % da referida composição, e pelo fato de pelo menos a camada externa ser formada a partir de uma composição que compreende como matriz polimérica uma composição poliamida escolhida no grupo que compreende: (i) um copolímero termoplástico obtido por copolimerização de <SYM>-caprolactama com pelo menos um dos monómeros escolhidos no grupo que compreende: um aminoácido que compreende pelo menos 9 átomos de carbono, ou a lactama correspondente; uma mistura de hexametilenodiamina com um diácido que compreende pelo menos 9 átomos de carbono, sendo que a relação ponderal entre <SYM>-caprolactama e o total hexametilenodiamina e diácido e/ou de aminoácido está compreendida entre 4 e 9, ou (ii) uma mistura de pelo menos o referido copolímero termoplástico e de pelo menos uma segunda poliamida ou copoliamida termoplástica obtida por polimerização de monómeros que compreendem menos 9 átomos de carbono. O teor ponderal do segundo polímero ou copolímero na matriz polimérica está compreendido entre 0 e 80% em peso, de preferência entre 0 e 40% em peso. A estrutura multicamada da presente invenção apresenta propriedades de barreira ao vapor de carburante elevadas e boas propriedades mecânicas como uma boa resistência ao craqueamento.
