Abstract
mistura de polímeros, substrato de metal revestido, e, artigo extrudado. trata-se da mistura de polímeros que inclui pelo menos 90% em peso de polímero de polietileno de baixa densidade (ldpe) e de 1% a 10% em peso de copolímero de ácido com base no peso total da mistura de polímeros. na mistura de polímeros, o polímero de ldpe tem um índice de fusão (i2) de 2 g/10 min a 8 g/10 min conforme determinado de acordo com astm d1238 e uma distribuição de peso molecular de 5 a 10,5. na mistura de polímeros, o copolímero de ácido é um produto de reação polimerizado de: pelo menos 60% em peso de etileno, com base no peso total dos monômeros presentes no copolímero de ácido de etileno; de 1% a 20% em peso de monômero de ácido monocarboxílico, com base no peso total dos monômeros presentes no copolímero de ácido de etileno; e de 0 a 20% em peso de monômero de acrilato de alquila, com base no peso total dos monômeros presentes no copolímero de ácido de etileno.
