A polymer bearing 1,3‐benzoxazine moiety in the side chain was synthesized successfully from poly(allylamine) based on a stepwise strategy consisted of three steps: (1) treatment of poly(allylamine) with salicylaldehyde to convert the amino group in the side chain into the corresponding o ‐(iminomethyl)phenol moiety, (2) reduction of the o ‐(iminomethyl)phenol to obtain the corresponding o ‐(aminomethyl)phenol moiety, and (3) formation of 1,3‐benzoxazine moiety by the reaction of the o ‐(aminomethyl)phenol with formaldehyde. The content ratio of benzoxazine moieties and o ‐(aminomethyl)phenol moieties in the polymer were tunable by varying amount of formaldehyde. The presence of o ‐(aminomethyl)phenol moieties exhibited a significant promoting effect on the crosslinking reaction.
