Abstract

"COPOLìMEROS EM BLOCOS HIDROGENADOS". A presente invenção é um copolímero e blocos hidrogenado compreendendo pelo menos dois blocos distintos de polímero aromático de vinila hidrogenado, e pelo menos um bloco de polímero de dieno conjugado hidrogenado, caracterizado pelo fato de compreender: a) um peso molecular médio numérico total (mn~ t~) de 30.000 a 120.000, sendo que cada bloco de polímero aromático de vinila hidrogenado (A) tem um Mn~ a~ de 5.000 a 50.000 e cada bloco de dieno conjugado hidrogenado (B) tem um Mn~ b~ de 4.000 a 110.000; e b) um nível de hidrogenação tal que cada bloco de polímero aromático de vinila hidrogenado tenha um nível de hidrogenação superior a 90 por cento e cada bloco de polímero de dieno conjugado hidrogenado tenha um nível de hidrogenação maior que 95 por cento.
