Abstract

"COMPOSIçãO RICA EM BORRACHA NATURAL E PNEU COM BANDA DE RODAGEM DESSA COMPOSIçãO". Esta invenção se refere a uma composição de borracha rica em borracha natural e a um pneu com banda de rodagem dessa composição. Uma substituição parcial da borracha natural na banda de rodagem de pneu rica em borracha natural é realizada pela inclusão de uma borracha copolimérica de trans 1,4-estireno/butadieno especializada, caracterizada por ter uma combinação de teor de estireno ligado e limitações de microestrutura. A composição de borracha para banda de rodagem de pneus é composta por uma mescla da borracha de trans 1,4-estireno/butadieno especializada e borracha natural de cis 1,4-poliisopreno, opcionalmente com pelo menos um elastómero à base de dieno adicional, em que a borracha natural permanece como a maior parte dos elastómeros na composição de borracha para banda de rodagem. Um aspecto significativo da invenção é uma substituição parcial da borracha de cis 1,4-poliisopreno natural na composição de borracha para banda de rodagem. A borracha de trans 1,4-estireno/butadieno especializada tem um teor de estireno ligado na faixa de 15 a 35 por cento e uma microestrutura de sua parte polibutadieno composta por 50 a 80 por cento de unidades isoméricas trans 1,4, 10 a 20 por cento de unidades isoméricas cis 1,4 e 2 a 10 por cento de unidades isoméricas vinila 1, 2; de preferência, um valor de viscosidade Mooney (ML1+4) a 100<198>C na faixa de 50 a 100, alternativamente de 50 a 85 e, de preferência, uma temperatura de transição de vidro (Tg) na faixa de -60<198>C a -90<198>C.
