Abstract

"APERFEIçOADOR DE ìNDICE DE VISCOSIDADE DE POLìMERO ESTRELA PARA COMPOSIçõES DE óLEO" Esta invenção refere-se a polímeros estrela que podem ser usados como aperfeiçoadores de índice de viscosidade em composiçãoes de óleo formuladas para motores de alta performance. Os polímeros estrela possuem braços de copolímero em tetrabloco de poliisopreno-polibutadieno-poliisopreno hidrogenados com um bloco de poliestireno e que fornece excelente performance a baixa temperatura em óleos lubrificantes, exibindo boa eficiência espessante, e são acabáveis como fragmentos de polímero.
