Abstract
Procedimiento de preparar gránulos copoliméricos, duros, reticulados y discretos, por polimerización con radicales libres en una dispersión acuosa de una mezcla monomérica que comprende por lo menos 50% en peso de monómero monoetilénicamente insaturado y menos de 50% en peso de monómero reticulante polietilénicamente insaturado que tiene por lo menos dos grupos activos etilénicamente insaturados, caracterizado porque la polimerización se realiza a una temperatura de 30 a 95ºC con oxígeno en contacto con y/o disuelto en la mezcla monomérica por lo menos hasta que se alcanza el punto de gelificación.
