Abstract

método de hidrogenação para polímero aromático e copolímero em bloco hidrogenado e seu uso. a presente invenção divulga um método de hidrogenação para um polímero aromático. o método compreende: colocar um polímero aromático em contato com um reagente de hidrogenação na presença de um catalisador de hidrogenação de modo a hidrogenar pelo menos alguns anéis aromáticos no polímero aromático, em que o catalisador de hidrogenação contém um transportador e um elemento de platina, um elemento do grupo iva e um elemento de metal de terras raras carregado no transportador, o transportador sendo alumina. a presente invenção também fornece copolímeros em blocos hidrogenados, copolímeros hidrogenados em cinco blocos e copolímeros hidrogenados em sete blocos. por meio do método de hidrogenação fornecido na invenção, o anel aromático no polímero aromático pode ser efetivamente hidrogenado para obter um grau mais elevado de hidrogenação do anel aromático, a influência na estrutura do polímero é pequena e a cadeia molecular do polímero aromático antes e depois da reação de hidrogenação não é essencialmente degradada. os copolímeros em blocos hidrogenados da presente invenção não só possuem alto grau de hidrogenação, mas também possuem alta transmitância de luz, baixa turbidez e excelente resistência ao impacto.
