Abstract
"PROCESSO DE SìNTESE DE NANOCOMPóSITOS DE POLIOLEFINAS DE ULTRA ALTO PESO MOLECULAR, E, NANOCOMPóSITO DE POLIOLEFINA DE ULTRA ALTO PESO MOLECULAR". A presente invenção refere-se a um processo de síntese de nanocompósitos de poliolefinas de ultra alto peso molecular e alta performance compreendendo duas etapas de polimerização, em que a primeira etapa consiste na polimerização in situ de uma olefina no espaçamento interlamelar de um filossilicato organofílico, de modo a se obter uma esfoliação eficiente das partículas do filossilicato na matriz polimérica, e a segunda etapa consiste na posterior polimerização de uma olefina realizada no meio compreendendo o nanocompósito de poliolefina obtido na primeira etapa de polimerização, de modo a se obter uma poliolefina de ultra alto peso molecular e com propriedades térmicas, mecânicas e de barreira melhoradas, enquanto mantendo as propriedades óticas.
