Abstract

MéTODO PARA PRODUçãO DE PéROLAS DE POLIESTIRENO EXPANSìVEL. O método da invenção consiste em alimentar correntes de polimero fundido e agente expansor para uma zona de mistura, dispersar o dito agente expansor no fundido polimérico sob agitação com alto cisalhamento em um primeiro misturador estático, mantendo a dita mistura no segundo misturador estático sob agitação simultânea com cisalhamento intenso, resfriar a dita mistura no terceiro misturador estático sob agitação simultânea até uma temperatura intermediária, resfriar a dita mistura até uma temperatura necessária para a granulação, extrudar filamentos poliméricos e subseqúentemente resfriá-los e granulá-los. Durante o processamento, a razão ponderal da vazão de fundido polimérico, G~ p~, para a vazão do agente expansor, G~ EA~, fica na faixa entre 13,0 e 19,0, a temperatura no primeiro misturador estático para misturação sob alto cisalhamento é calculada de acordo com a fórmula (1), no segundo e no terceiro misturadores estáticos ela é calculada de acordo com as fórmulas (II) e (III), respectivamente, onde G~ EAmax~ é vazão máxima possível do agente expansor, G~ EAcorrente~ é a vazão corrente usada do agente expansor, e a razão do índice de fluidez (MFI) para o peso molecular ponderal médio (M~ w~) fica na faixa entre (0,8 a 12,0) x 10^ -5~. O método torna possível produzir poliestireno na forma de grânulos expansíveis, dentro de uma ampla faixa de pesos moleculares, e um poliestireno resistente a impacto.
