Abstract
La presente invención se refiere a un perfeccionamiento del procedimiento de polimerización en masa de radicales libres para la preparación de un polímero de masa molecular elevada a partir de un monómero aromático del vinilo. Este procedimiento se caracteriza porque la polimerización se efectúa en presencia de un catalizador ácido que presenta a 25ºC un pKa inferior a 2 o en presencia de una de sus sales. El perfeccionamiento consiste en dispersar el catalizador ácido o sus sales, en un ácido acrílico o metacrílico, o en uno de sus ésteres, antes del contacto con el monómero acromático de vinilo. Este ácido acrílico o metacrílico o los ésteres correspondientes permiten la dispersión del catalizador ácido en el interior del monómero ácido de vinilo sin provocar la polimerización catiónica. El catalizador ácido o la sal correspondiente cataliza la reacción de polimerización de los radicales libres para producir en plazos de reacción razonables polímeros de masa molecular elevada.
