DOUBLE NETWORK HYDROGEL WITH ANIONIC POLYMER AND USES THEREOF

A double network hydrogel consists of a first network and a second network, where the first network is, or includes, a first polymer that is formed, at least in part, of -CH2-CH(OH)- units, and the second network is, or includes, a second polymer that is formed, at least in part, of carboxyl (COOH)-...

Beschreibung
Zusammenfassung:	A double network hydrogel consists of a first network and a second network, where the first network is, or includes, a first polymer that is formed, at least in part, of -CH2-CH(OH)- units, and the second network is, or includes, a second polymer that is formed, at least in part, of carboxyl (COOH)-containing units or salts thereof, sulfonyl (SO3H)-containing units or salts thereof, and at least one of hydroxyl (OH)-containing units or amino (NH2)-containing units, where the hydrogel may be used as a cartilage replacement. La présente invention concerne un hydrogel à double réseau qui est constitué d'un premier réseau et d'un deuxième réseau, le premier réseau étant, ou comprenant, un premier polymère qui est formé, au moins en partie, de motifs -CH2-CH(OH)-, et le deuxième réseau est, ou comprend, un deuxième polymère qui est formé, au moins en partie, de motifs contenant carboxyle (COOH) ou des sels de ceux-ci, motifs contenant sulfonyle (SO3H) ou des sels de ceux-ci, et au moins un motif contenant hydroxyle (OH) ou motifs contenant amino (NH2), l'hydrogel pouvant être utilisé en tant que remplacement de cartilage.
