Abstract

Patente de Invenção: <B>"PROCESSO PARA A PREPARAçãO DE MISTURAS DE POLISSULFETO DE áCIDO DITIOFOSFóRICO"<D>. A invenção refere-se a um processo para a preparação de misturas de polissulfeto de ácido ditiofosfórico, caracterizado pelo fato de se reagir dissulfetos de ácido ditiofosfórico com enxofre a temperaturas elevadas. As misturas de polissulfeto de ácido ditiofosfórico preparadas de acordo com a presente invenção são empregadas como distribuidoras de enxofre para a vulcanização de borracha natural ou sintética bem como na vulcanização de látex de látex de borracha natural ou sintética.
