Abstract

polímeros de moldagem por sopro tratados com peróxido com intumescimento de peso aumentado e intumescimento de molde constante. trata-se de polímeros à base de etileno em geral caracterizados por um índice de fluidez de alta carga menor que 12 g/10 min, um peso molecular ponderal médio de 200000 a 550000 g/mol, um peso molecular numérico médio de 18000 a 48000 g/mol, um parâmetro cy-a menor que 0,12, uma tan d a 0,1 s-1 de 0,5 a 0,9 graus, uma tan d a 100 s-1 de 0,5 a 0,75 graus, e uma viscosidade a 0,001 s-1 de 1,3 x 106 a 1 x 107 pa-s. esses polímeros de etileno podem ser produzidos por tratamento com peróxido de uma resina catalisada por metaloceno duplo de distribuição de peso molecular bimodal e podem ser usados para produzir garrafas moldadas por sopro e outros produtos moldados por sopro.
