Abstract

"COMPOSIçãO DE ELASTÈMERO TERMOPLáSTICO ISENTA DE GEL, PROCESSOS PARA A PREPARAçãO DE UMA COMPOSIçãO DE ELASTÈMERO TERMOPLáSTICO ISENTA DE GEL, PROCESSO PARA A PREPARAçãO DE UM ARTIGO MANUFATURADO E ARTIGO MANUFATURADO". Composições de elastómero termoplástico de reologia modificada, livre de gel, compreendendo uma mistura fundida de um polímero etileno/<244>olefina e um polímero de alta fusão tal como polipropileno ou um copolímero propilenol <244>-olefina em que a modificação de reologia é induzida por uma combinação de um peróxido e um co-agente de radical livre em uma proporção peróxido: co-agente de 1:4 a 1:20 e uma concentração máxima de peróxido de 0,075 % em peso. As composições resultantes têm uma fase elastomérica, uma fase não elastomérica e certas propriedades fisicas que excede aquelas de uma composição semelhante que é modificada a reologia por peróxido sozinho ou peróxido e co-agente em uma proporção 1:2 a 2:1. As composições são usadas para fazer uma variedade de artigos de manufatura, tais como tubulação, faixa de tempo, via calandragem, extrusão e técnicas de moldagem, tal como moldagem por sopro.
