Abstract

"DOSAGEM CONTìNUA DE INICIADORES EXTREMAMENTE RáPIDOS DURANTE AS REAçõES DE POLIMERIZAçãO". A invenção refere-se a um processo no qual iniciadores que tem uma meia-vida de a partir de 0,0001 hora até 0,05 hora na temperatura de polimerização são dosados para uma mistura de polimerização. A dosagem de tal iniciador permite um controle melhorado da velocidade de polimerização e velocidades de polimerização mais rápidas, e o processo irá resultar em um polímero com níveis muito baixos de iniciador residual.
