Abstract

"MICROCáPSULAS COMPREENDENDO CIANOACRILATOS DE POLIALQUILA". A invenção relaciona-se às microcápsulas enchidas com gás que consistem em cianoacrilatos de polialquila, que são produzidos por copolimerização de um ou mais cianoacrilatos de alquila com um monómero funcional e/ou por hidrólise parcial da cadeia lateral de um cianoacrilato de polialquila, bem como a um processo para a produção de microcápsulas enchidas com gás e ao seu uso para a diagnose por ultra-som.
