Crosslinked polymer that can be obtained from the polymerization of: (i) at least one monomer of formula (I) (CH2> = CR1) CO-K (I) in which: - K represents OZ or NH-Z , representing Z (CR2R3) m-CH3, (CH2-CH2-O) mH, (CH2-CH2-O) m-CH3, (CH2) m-NR4R5, with m representing an integer from 1 to 30; - R1, R2, R3, R4 and R5 independently represent H or a C1-C6 alkyl; (ii) at least between 0.1 and 50 mol%, advantageously between 1 and 30 mol%, more advantageously between 1 and 20 mol% of a cyclic monomer having an exomethylene group of formula (II): * * Formula ** in which: - R6, R7, R8 and R9 independently represent H or an aryl group of C5-C7 or R6 and R9 are absent and R7 and R8 form together with the carbon atom to which a group is attached C5-C7 aryl; - i and j independently represent an integer selected between 0 and 2; - X represents O or X is not present and in the latter case, CR6R7 and CR8R9 are linked by a single CC link and (iii) at least one bioabsorbable block copolymer crosslinker, in which the bioabsorbable block copolymer crosslinker is linear and has groups (CH2> = (CR10)) - at both ends, in which R10 independently represents H or a C1-C6 alkyl. |
