Abstract

"NANOPARTìCULAS POLIMéRICAS QUE INCLUEM COMPONENTES OLFATIVOS". As nanopartículas poliméricas que incluem componentes olfativos têm uma temperatura de transição vítrea de > 50<198>C. Elas podem ser obtidas por adição contínua de um componente monómero e de um componente olfativo a uma solução aquosa. A solução aquosa compreende um primeiro iniciador e um emulsificante. Os componentes adicionados são distribuídos na solução aquosa para se obter uma mistura da reação enquanto se inicia a polimerização do componente monómero à primeira temperatura. O componente monómero líquido e o componente olfativo são adicionados continuamente enquanto é adicionado gota a gota um segundo iniciador à mistura da reação e é mantida a primeira temperatura. Após terminada a adição do componente monómero líquido e do componente olfativo a temperatura da mistura da reação é aumentada até uma segunda temperatura e é adicionado gota a gota um terceiro iniciador.
