Abstract

"COMPOSIçàO DE BORRACHA VULCANIZáVEL, PROCESSO DE PREPARAçãO DE UMA COMPOSIçãO DE BORRACHA, E, INVóLUCRO DE PNEUMáTICO"<D> A presente invenção refere-se a uma composição de borracha vulcanizável que é utilizável para a fabricação de invólucros de pneumáticos, um processo de preparação desta composição e um invólucro de pneumático cuja banda de rodagem compreende uma tal composição, esta última apresentando propriedades histeréticas e físicas melhoradas no estado vulcanizado, ao mesmo tempo conservando propriedades de emprego satisfatórias. Uma composição de acordo com a invenção compreende uma carga branca de reforço e ela é tal que compreende, pelo menos, um copolímero diênico com blocos que é destinado a interagir com a referida carga branca de reforço e que compreende, em uma pelo menos de suas extremidades de cadeia, um bloco polissiloxano terminando por um grupo trialquilsilila, o referido bloco respondendo à fórmula: [-(SiR~ 1~R~ 2~O)-]~ x~- SiR~ 3~R~ 4~R~ 5~, onde R~ 1~R~ 2~, R~ 3~R~ 4~ e R~ 5~ representam grupos alquila tendo de 1 a 20 átomos de carbono e onde x é um inteiro natural não nulo.
