Claims21
A carbon dioxide-reversibly-protected chain extension-crosslinking agent having a chemical structure represented by Formula I, Formula II, Formula III or Formula IV:
- wherein, n, m and p are integers, R is either OCH2CH(CH3) or OCH2CH2, 1≤n≤20, 1≤m≤10, and 1≤p≤10.
A preparation method of a carbon dioxide-reversibly-protected chain extension-crosslinking agent, the method comprising:
- dissolving aliphatic diamine or aliphatic triamine with 20 carbon atoms or fewer in an organic solvent to form a reaction mixture, and
- stirring the reaction mixture for a reaction under an atmosphere of carbon dioxide gas to obtain the carbon dioxide-reversibly-protected chain extension-crosslinking agent,
- wherein the aliphatic diamine is aliphatic alkane diamine, aliphatic ether diamine or aliphatic ester diamine, and the aliphatic triamine is aliphatic alkane triamine.
