Abstract

"MISTURAS DE PARTIDA ATIVADAS E PROCESSOS A ELAS RELACIONADOS". A presente invenção refere-se a uma mistura de partida ativada que pode ser usada para preparar polioxialquileno polióis. A presente invenção refere-se também a um processo para preparação de uma mistura de partida ativada, particularmente a um processo para preparação de uma mistura de partida ativada constituída por um composto de partida de baixo peso molecular. A presente invenção refere-se também a um processo em batelada ou semibatelada para poliadição de um óxido de alquileno em uma mistura de partida ativada, particularmente em uma mistura de partida ativada que é constituída por um composto de partida de baixo peso molecular. A presente invenção provê uma mistura de partida ativada, particularmente uma mistura de partida ativada que é composta de um composto de partida de baixo peso molecular, que rapidamente inicia a polimerização. A presente invenção pode eliminar a necessidade de se sintelizar compostos de partida de alto peso molecular custosos por catálise com KOH em/um reator separado, dedicado.
