Abstract
"COMPOSIçõES DE ELASTÈMERO, E PNEUMáTICOS COM BANDAS DE RODAGEM FABRICADAS COM ELAS". Esta invenção descreve o uso de copolímeros líquidos em bloco de butadieno-isopreno com aproximadamente 25.000 a 100.000 de peso molecular viscosimétrico médio, compreendendo entre 10 e 90% em peso de isopreno e entre 90 a 10% em peso de butadieno. Este material é adicionado a um composto de borracha que contém borracha natural, borracha de isopreno, borracha de butadieno-estireno e borracha de butadieno, ou suas misturas, a soma das quais sendo igual ou maior do que 50 phr da formulação com teor total de borracha. O copolímero líquido em bloco é usado em níveis baixos, tipicamente entre 1,5 phr e 15 phr. A invenção também inclui pneumático com pelo menos um componente composto de tal composição de borracha, como uma banda de rodagem de pneumático.
