Abstract

"PROCESSOS DE PREPARAçãO DE MICROCáPSULAS POR POLICONDENSAçãO DE UMA MISTURA DE RESINA DE MELAMINA/FORMALDEìDO E DE USO DE MICROCáPSULAS, MICROCáPSULA, MISTURA DE RESINA DE MELAMINA/FORMALDEìDO, E, USO DE UMA MISTURA DE RESINA DE MELAMINA/FORMALDEìDO". Microcápsulas são preparadas por policondensação de uma mistura de resina de melamina/formaldeído em água, na qual material essencialmente insolúvel em água formador do núcleo da cápsula está disperso, na presença de um colóide protetor aniónico, por meio de um processo no qual a mistura de resina de melamina/formaldeído é composta de: a) uma solução aquosa de um condensado de: a1) 1 mol de melamina, a2) de 2 a 5 moles de formaldeído e a3) de 0 a 0,5 mol de um derivado de melamina que pode sofrer uma reação de adição ou de condensação com formaldeído e a4) de 1 a 5 moles de um C~ 1~-C~ 3~-alcanol e b) de 0,01 a 1 mol de uma amina primária, secundária ou terciária solúvel em água ou amónia.
