Abstract
Procedimiento para la preparación de polímeros de N-vinilamida mediante polimerización de una amida terciaria de ácido N-vinilcarboxílico, eventualmente junto con un compuesto olefinicamente insaturado capaz de copolimerización, en presencia de un hidrocarburo alifático inerte a una temperatura de 0 hasta 150ºC y en presencia de iniciadores radicalmente activos, que se caracteriza porque la polimerización se realiza en presencia de (a) un iniciador, que es soluble en la amida monómera de ácido N-vinilcarboxílico en condiciones normales e insoluble en el hidrocarburo empleado y (b) de un iniciador, que es soluble en el hidrocarburo empleado en condiciones normales.
