Abstract

<B>Patente de Invenção para: ''POLIMERIZAçãO DE SILOXANOS''<D> Processo para polimerização de siloxanos usando um catalisador de fosfazeno, em que um siloxano tendo grupos R' silicone-ligados, em que R'representa um grupo hidroxila ou um grupo hidrocarbonóxi tendo 1 a 8 átomos de carbono, é misturado com um siloxano cíclico ou linear não tendo grupos R' silicone-ligados e com um catalisador à base de fosfazeno e se deixa polimerizar de tal maneira que o siloxano tendo grupos R' silicone-ligados condensa e o siloxano cíclico e linear não tendo grupos R' silicone-ligados polimeriza por equilíbrio.
