Abstract

ELASTÈMEROS DE DIENO EM FASE GASOSA"<D>. A invençmonómeros de dieno conjugados, que são úteis para produzir anionicamente polímeros de dieno ramificaha de estireno butadieno, borracha de poibutadienoadores compreendem uma partícula metalatável, tal como uma borracha ligada, um polímero termoplástico ou um elastómero curado, que é metalatado multiplamente com átomos de metal alcalino do Grupo IA. Os polímeros de dieno multi-ramificados obtidos po os catalisadores exibem propriedades desejáveis, tais como um peso molecular extremamente alto, uma distribuição de peso molecular, Tg e teor de vinila controlados, e a capacidade de absorver prontamente solventes de hidrocarboneto e óleos. Os polímeros são facilmente misturados para formar compostos elastoméricos vulcanizáveis e artigos, tais como pneus, que têm excelente resistência ao desgaste e à ruptura e exibem propriedades de histerese reduzida.
