Abstract

Patente de Invenção:<B>"MéTODO DE PRODUçãO DE LIOGéIS ESFéRICOS SUBSTANCIALMENTE EM AGENTES DE SILILAçãO INSOLúVEIS EM áGUA"<D>. Um método de produção de liogéis substancialmente esféricos em agentes de sililação insolúveis em água. A presente invenção refere-se a um método de produção de liogéis substancialmente esféricos nos quais a) um liogel é fornecido, b) o liossol obtido em etapa a) é transferido para pelo menos um agente de sililação no qual o liossol é insolúvel, e c) o liossol esférico formado em etapa b) é gelatinizado em pelo menos um agente de sililação no qual o liossol é igualmente insolúvel, para produzir o liogel.
