Abstract

"PROCESSO DE POLIMERIZAçãO EM SUSPENSãO AQUOSA DO CLORETO DE VINILA". No processo, de acordo com a invenção, para a polimerização em suspensão aquosa do cloreto de vinila, o elemento de atração de polimerização compreende pelo menos um composto escolhido dentre os peroxidicarbonatos de dialquila, os peróxi-terc-alcanoatos e os peróxidos de diacila e utiliza-se, como agente de parada de polimerização, um radical estável de tipo nitróxido. As resinas assim obtidas apresentam uma boa brancura.
BRPI0207637-3A 2001-04-02 2002-03-28 processo de polimerização em suspensão aquosa do cloreto de vinila sozinho ou em mistura com menos de 50% de um outro monÈmero vinìlico, polìmeros e copolìmeros à base de cloreto de vinila. BR0207637B1 (pt)
