Abstract

Se ha descubierto de manera inesperada que varios compuestos, tales como éteres de alquil tetrahidrofurfurilo, pueden utilizarse para modificar polimerizaciones aniónicas de monómeros de dieno conjugado. Estos modificadores pueden utilizarse para polimerizar monómero de isopreno para dar 3,4-poliisopreno superior a excelentes velocidades de polimerización. Esto está en contraste con los modificadores tales como tetrametiletilen diamina que se utilizan típicamente para modificar dichas polimerizaciones. Esta invención expone más específicamente un proceso para la síntesis de 3,4-poliisopreno que comprende polimerizar el monómero de isopreno en un solvente orgánico en la presencia de un sistema catalizador que está comprendido de (a) un iniciador de litio y (b) etiltetrahidrofurfruil éter.
