Abstract

"PROCESSO PARA PRODUZIR POLIDIORGANOSSILAXONO PARCIALMENTE BLOQUEADO TERMINALMENTE COM GRUPOS SILETILENO SUBSTITUìDOS". Este relatório descreve e reivindica um processo para produzir polidiorganossiloxanos parcialmente bloqueados terminalmente com grupos siletileno substituídos. O processo compreende as etapas de: A) misturar um polidiorganossiloxano bloqueado terminalmente com hidroxila com um composto contendo silício tendo, pelo menos, dois átomos de hidrogênio ligados a silício, e um siloxano bloqueado terminalmente com -Si(R')~ 3~ na presença de um catalisador de polimerização ácido para formar uma mistura em que cada R' independentemente denota um hidrocarboneto monovalente ou halo-hidrocarboneto tendo 1 a 6 átomos de carbono, B) conduzir uma reação com a mistura da etapa A de modo a produzir um polidioganossiloxano tendo pelo menos um átomo de hidrogênio ligado a silício e pelo menos um grupo -Si(R')~ 3~, e C) adicionar um alquenilsilano substituído na presença de um catalisador de hidrossililação para o produto de reação obtido da etapa B para formar um polidiorganossiloxano parcialmente bloqueado terminalmente com grupos siletileno substituído. Um extensor de cadeia também pode ser incluído com a mistura de reação da etapa A e/ou o produto de reação da etapa B. Os polidiorganossiloxanos são apropriados para uso em composições selantes.
