CPC C08F 220/1804 (2020.02) [C09J 177/00 (2013.01); C08K 5/053 (2013.01)] | 17 Claims |
1. An adhesive composition comprising multiple chains of a copolymer including a first co-monomer selected from one of dopamine methacrylamide, 3,4-dihydroxyphenylalanine or 3,4-dihydroxystyrene, and a second co-monomer comprising a pendant first functional group;
wherein at least two of the first functional groups of different copolymer chains are interlinked non-covalently via:
a neutral hydrogen bond formed between the first functional groups of the interlinked first and second copolymer chains, wherein in the neutral hydrogen bond the following relationship is met: ΔpKa=pKa (DH)−pKa (AH+)>0, wherein pKa (DH) is the pKa value of a hydrogen bond donor and pKa (AH+) is the pKa value of a hydrogen bond acceptor;
a first additive comprising second and third functional groups, each of which form neutral hydrogen bonds with said first functional groups of different copolymer chains; or
a second additive, which is a metal ion, to which said first functional groups of different copolymer chains are bound through a ligand-metal-ligand bond, the first functional groups forming the ligands.
