Abstract
uma poliolefina reciclada homogênea compreendendo polietileno e polipropileno, caracterizada por compreender: a) de 1 a 10.000 ppm de impurezas solúveis; b) de 0,001 a 5% em peso de impurezas insolúveis, que são partículas com uma dimensão máxima de 20 micrômetros a 1 mm, em peso total da poliolefina reciclada; c) de 0,0005 a 1% (5 a 10.000 ppm) de solvente possuindo um parâmetro de hansen dh de 0 a 3; e d) a partir de 0,1 ppm a 10.000 ppm de um auxiliar de filtração que possui um parâmetro de hansen dh > 10; que pode ser obtida a partir de um método que compreende as etapas de: a) misturar resíduos contendo poliolefinas com um solvente possuindo um parâmetro de hansen dh de 0 a 3; b) colocar esta mistura em contato com um auxiliar de filtração que possui um parâmetro de hansen dh maior do que 10; e c) separar a poliolefina da mistura.
