Abstract

PROCESSO PARA A PREPARAÇçO DE FIOS POLIMÉRICOS A PARTIR DE HOMOPOLÍMEROS OU COPOLÍMEROS DE ULTRA ALTO PESO MOLECULAR, FIOS POLIMÉRICOS, ARTIGOS POLIMÉRICOS MOLDADOS, E, USO DE FIOS POLIMÉRICOS. A presente invenção se refere a um processo para a preparação de fios de alto desempenho de homopolímeros ou dc copolímeros de ultra alto peso molecular obtidos a partir de monômeros C~ 2+n~,com n variando de O a 2, com distribuição de peso molecular mono-, bi- ou multimodal. A invenção também se refere aos fios assim obtidos e aos artigos fabricados a partir dos fios de alto desempenho. Mais especificamente, o processo da presente invenção utiliza um polietileno de ultra alto peso molecular (PEUAPM) com distribuição de peso molecular bimodal de reator ou multimodal. Fios de homopolímeros ou copolímeros à base de polietileno de ultra alto peso molecular (PEUAPM) e de polipropileno de alto peso molecular em mistura com PEUAPM vêm sendo amplamente utilizados em diversas aplicações que exijam alta tenacidade e elevada resistência química, combinadas com leveza. Tais aplicações estão relacionadas com a fabricação de tecidos balísticos, cordas, linhas de pesca, filtros químicos e separadores de células eletrolíticas substituindo o amianto, roupas e produtos específicos para esportes, e tecidos para pára-quedas e capacetes. O presente processo de preparação de fios à base de homopolímeros e copolímeros de ultra alto peso molecular difere dos processos tradicionais, principalmente, devido aos seguintes aspectos: (i) a utilização de homopolímeros ou copolímeros com perfis de peso molecular bimodal ou multimodal, sendo selecionados, preferencialmente, dentre um homopolímero ou um copolímero bimodal de reator, o qual facilitará a processabilidade do gel e tomará possível a operação
