| abstract |
The invention discloses a dynamic polymer with a hybrid cross-linked network, which comprises dynamic covalent cross-linking and supermolecule hydrogen bond cross-linking; wherein the dynamic covalent crosslinks are effected by organoborate silicone linkages, the dynamic covalent crosslinks reaching above the gel point in at least one of the crosslinked networks; the supermolecule hydrogen bond crosslinking is formed by side groups and/or side hydrogen bond groups on the side chains. The dynamic polymer combines dynamic covalent organic boric acid silicon ester bonds with supermolecule hydrogen bonds, and can prepare dynamic polymers with rich structures and various performances by regulating and controlling the structures of reactants. The dynamic polymer can be used for manufacturing shock absorption buffer materials, impact resistance protection materials, self-repairing materials, toughness materials and the like. |
