description PROCESSO PARA A PRODUçãO DE PARTES MOLDADAS DE MATERIAIS POLIMéRICOS NANOPOROSOS. A invenção refere-se a um processo para produzir partes moldadas de materiais poliméricos nanoporosos, compreendendo as seguintes etapas: a) produzir uma mistura polimérica de multifases, tendo domínios na faixa entre 5 a 200 mm, b) impregnar a mistura polimérica com um agente de expansão, a solubilidade do agente de expansão durante a fase que forma os domínios sendo pelo menos duas vezes tão elevados quanto nas fases adjacentes, c) expandir a mistura polimérica de multifases compreendendo o agente de expansão, pela introdução da mistura polimérica dentro de uma cavidade e sua expansão ali, assim obtendo-se a parte moldada. Process for the production of moldings from nanoporous polymer materials, comprising the stages of a) preparation of a multiphase polymer mixture with domains in the range from 5 to 200 nm, b) impregnation of the polymer mixture with a blowing agent, where the solubility of the blowing agent in the phase forming the domains is at least twice as high as in the adjacent phases, c) expansion of the multiphase polymer mixture comprising blowing agent, by introducing the polymer mixture into a cavity and expanding it therein, thus obtaining the molding.
