Abstract

"AUMENTO DO RENDIMENTO DE REATOR DE POLIMERIZAçãO USANDO-SE UM SISTEMA INICIADOR ESPECìFICO". A presente invenção refere-se a um processo para polimerizar um ou mais monómeros em que são usados, no máximo, 90% em peso/peso de uma quantidade que pode ser usada com segurança de um primeiro iniciador e um segundo iniciador é dosado pelo menos após o início da polimerização, em uma quantidade tal que seja usada essencialmente a inteira capacidade de resfriamento do reator de polimerização, resultando em um processo eficiente quanto ao custo para a obtenção de polímeros, particularmente de polímeros que compreendam cloreto de vinila polimerizado.
