  • Patent number: 8101670
    Abstract: The present invention discloses polymers prepared through the Diels-Alder reaction with benzoxazine groups in their main chains. Moreover, polymers with high molecular weight could be successfully prepared via this method. Furthermore, the mentioned polymers are able to undergo crosslinking reaction by heat treatment. Heat energy causes the ring-opening reaction of benzoxazine in polymer main chains to undergo crosslinking reaction, and cross-linked polymers are thereby formed with great flexibility and high crosslinking degree.
