Abstract

Patente de Invenção "PROCESSO PARA A PREPARAçãO DE UM COPOLìMERO". Processo para a preparação de um copolímero em bloco compreendendo um primeiro bloco de polímero de um monómero anionicamente polimerizável selecionado do grupo que consiste de hidrocarbonetos monovinil aromáticos, dienos de conjugados e misturas dos mesmos e um segundo bloco de polímero de polidimetilsiloxano, o dito processo compreende as etapas de: (a) combinar a uma temperatura de desde -10 até 60‹ em uma mistura da reação pelo menos o (s) monómero (s) anionicamente polimerizável (is), um iniciador organo de metal alcalino, hexametilciclotrisiloxano e um promotor polar, efetuando desse modo a polimerização do (s) monómero (s) anionicamente polimerizável (is); (b) permitir que se processe a polimerização até que a polimerização em bloco do (s) monómero (s) anionicamente polimerizável (is) e a reação de pertubação subsequente entre as cadeiras ativas de polímero e hexametilciclotrisiloxano esteja completa; (c) aumentar a temperatura até uma temperatura na fixa de desde 60 até 120‹C, efetuando assim a polimerização do hexametilclotrisiloxano na extremidade do bloco de polímero ativo obtido na etapa (a); e (d) terminar a polimerização.
