发明名称 PROCESSO PARA A PRODUCAO DE MICROCAPSULAS QUE CONTEM UM MATERIAL LIQUIDO DE ENCHIMENTO;MICROCAPSULAS E MATERIAL EM FOLHA
摘要 <p>In a process for the production of microcapsules containing a liquid fill material, a dispersion-stabilizing species is produced in an aqueous acidic medium by interaction of a melamine formaldehyde precondensate and a water soluble polymer, neither of which alone is dispersion stabilizing with respect to the liquid fill material, and the precondensate is condensed by acid catalysis to produce a condensate which separates from solution and enwraps the liquid fill material to produce microcapsules.</p>
