Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A polybenzoxazine bearing allyl group in the side chain was synthesized by the ring‐opening polymerization of <italic>N</italic>‐allyl‐benzoxazine and was crosslinked by the two different processes, (1) thermally induced oligomerization of the allyl side chains and (2) radical addition of dithiol (thiol‐ene reaction) to the allyl side chains. The former process was promoted by adding 2, 5‐dimethyl‐2, 5‐di(<italic>tert</italic>‐butylperoxy)hexane as a radical source, leading to the improved yield of the networked polymer isolated as acetone‐insoluble fraction. The thiol‐ene reaction with using 1, 6‐hexanedithiol was also an efficient method for crosslinking the polybenzoxazine. © 2013 Wiley Periodicals, Inc.
