Abstract
Se refiere a interpolímeros monomeros aromáticos alfa-olefina/vinil con senales características en su espectro de MNR carbono 13. En particualr, loscopolímeros etileno/estireno presentan picos en el espectro de NMR carbono 13 que aparecen en elrango de cambio químico (chemical shift) de 43,70 - 44,25uím ppm, preferentemente entre 43,75 - 44,25 ppm y 38,0 - 38,5 ppm, dichos picos son por lo menos tres veces el pico hasta el ruido pico. Losinterpolímeros se preparar mediante la polimerizacion de la mezcla apropiada de monomeros en presencia de un catalizador tal como (dimetilsilanodil(2-metil-4-fenilindenil)zirconio dicloruro racémico. Los polímeros poseen un modulo incrementado segun se determina mediante stress de tension/esfuerzo y datos demecánica dinámica a niveles de monomero vinil aromático comparables. También se propone un procedimiento para preparar dichos interpolímeros.
