Abstract

"PROCESSO PARA PREPARAR UM MICROGEL, MICROGEL, COMPOSIçãO DE REVESTIMENTO E ARTIGO MOLDADO". A invenção apresenta, em um aspecto, um processo para a preparação de um microgel através de polimerização RAFT na presença de um agente de transferência de cadeia de RAFT, um ou mais monómeros solvofóbicos, e um ou mais monómeros solvofílicos, para formar um ou mais copolímeros de bloco que compreendem um ou mais blocos solvofóbicos e um ou mais blocos solvofílicos, sendo que o bloco solvofóbico é insolúvel em um meio de dispersão e o bloco solvofílico é solúvel no meio de dispersão. O copolímero de bloco é disperso no meio de dispersão para formar micelas, as quais são então estabilizadas para formar o microgel. O meio de dispersão pode ser aquoso ou lipofílico. O método da presente invenção também permite a encapsulação de uma grande variedade de materiais, tais como pigmentos, moléculas de corantes, e flocos de alumínio utilizados em pinturas metalizadas.
