Abstract
"PROCESSO PARA A PREPARAçãO DE POLìMEROS VINIL AROMáTICOS, E, CONTAS EXPANSìVEIS DE POLìMEROS VINIL AROMáTICOS". Processo para a preparação de polímeros vinil aromáticos expansíveis, que compreende: a) a polimerização em suspensão aquosa de pelo menos um monómero vinil aromático na presença de um agente de suspensão escolhido de sais inorgânicos do ácido fosfórico; b) a recuperação de contas expansíveis do recipiente de reação; c) a lavagem das contas assim obtidas com uma solução aquosa contendo 0,005 - 2% de um agente não iónico ativo na superfície; d) a recuperação das contas lavadas, substancialmente sem nenhum sal inorgânico do ácido fosfórico, na superfície, e a secagem das mesmas em uma corrente de ar.
