MICROCAPSULES COMPRISING FUNCTIONALISED POLYALKYLCYANOACRYLATES

The invention relates to gas-filled microcapsules that consist of functionalized polyalkylcyanoacrylates that are produced by copolymerization of one or more alkylcyanoacrylates with a functional monomer and/or by partial side-chain hydrolysis of a polyalkylcyanoacrylate, as well as a process for th...

Beschreibung
Zusammenfassung:	The invention relates to gas-filled microcapsules that consist of functionalized polyalkylcyanoacrylates that are produced by copolymerization of one or more alkylcyanoacrylates with a functional monomer and/or by partial side-chain hydrolysis of a polyalkylcyanoacrylate, as well as a process for the production of gas-filled microcapsules and their use for ultrasound diagnosis. L'invention concerne des microcapsules remplies de gaz constituées de polyalkylcyanoacrylates fonctionnalisés qui sont produits par copolymérisation d'un ou de plusieurs alkylcyanoacrylates avec un monomère fonctionnel et/ou par hydrolyse partielle de chaînes latérales d'un polyalkylcyanoacrylate. Elle concerne aussi un procédé de production de microcapsules remplies de gaz et leur utilisation dans les diagnostics par ultrasons.
