Title (EN) BRANCHED POLYMERS
(FR) POLYMÈRES RAMIFIÉS
Abstract:
(EN) The present invention relates to branched polymer comprising a support moiety and at least three block co-polymer chains covalently coupled to and extending from the moiety, wherein: (i) each of the at least three block co-polymer chains comprise (a) a cationic polymer block that is covalently coupled to a hydrophilic polymer block, or (b) a cationic polymer block that is covalently coupled to a hydrophobic polymer block, said hydrophobic polymer block being covalently coupled to a hydrophilic polymer block; and (ii) at least one of said covalent couplings associated with each of said block co-polymer chains is biodegradable.
(FR) La présente invention concerne un polymère ramifié comprenant un fragment de support et au moins trois chaînes de copolymères séquencés couplées par liaison covalente au fragment et s'étendant à partir de celui-ci, où : (i) chacune des au moins trois chaînes de copolymères séquencés comprend (a) un bloc polymère cationique couplé par liaison covalente à un bloc polymère hydrophile, ou (b) un bloc polymère cationique couplé par liaison covalente à un bloc polymère hydrophobe, ledit bloc polymère hydrophobe étant couplé par liaison covalente à un bloc polymère hydrophile ; et où (ii) au moins un desdits couplages par liaison covalente associés à chacune desdites chaînes de copolymères séquencés est biodégradable.
