Abstract
"COMPOSIçõES DE BORRACHA CONTENDO SìLICA COM PRIMEIROS E SEGUNDOS AGREGADOS CADA UM CONTENDO DIFERENTES TAMANHOS DE PARTìCULAS" O presente pedido se refere a uma composição de borracha contendo uma carga de sílica precipitada com primeiros e segundos agregados. Os primeiros agregados são de 10 a 90 por cento em peso do peso total da sílica com primeiros e segundos agregados. Os segundos agregados variam de 90 a 10 por cento em peso do peso total da sílica com primeiros e segundos agregados. Os primeiros agregados consistem essencialmente em partículas que variam em tamanho de 5 a 15 nanómetros de diâmetro. Os segundos agregados consistem essencialmente em partículas que variam em tamanho de 17 a 30 nanómetros de diâmetro. A distribuição de tamanhos de poros da sílica, conforme medida por porosimetria de mercúrio, é monomodal.
