Abstract

POLIISOPRENO RAMIFICADO DE SÍNTESE RETICULÁVEL E PROCESSO DE SÍNTESE DE UM POLIISOPRENO A invenção refere-se a poliisoprenos ramificados sintéticos apresentando uma macroestrutura e uma microestrutura muito próximas daquelas da borracha natural. De acordo com um aspecto da invenção, estes poliisoprenos apresentam um estresse aparente F/S0 igual ou superior a 0,4 MPa para um alongamento relativo (alfa) de 150 %, aplicado em um corpo de prova em forma de haltere constituído de poliisopreno reticulável. De acordo com um outro aspecto da invenção, estes poliisoprenos satisfazem a relação (i): Cotan (delta) (maior igual) 0,3761. (eta)inh + 0,15, em que cotan (delta) é a cotangente do ângulo de perdas de uma amostra do referido poliisopreno, medida a 130°C por meio de um aparelho com denominação comercial <<RPA2000>>, sendo que referida amostra é submetida a esforços de cisalhamento a 10 % de deformação e a uma freqüência de solicitações de 0,035 Hz, e em que (eta)inh é a viscosidade inerente do referido poliisopreno, medida em tolueno a 25°C e a uma concentração do referido poliisopreno em tolueno de 0,1 g/dl.
