“…8 We have also noticed a recent real industrial interest in exploiting elemental sulfur in polybenzoxazine-based materials, 9 in addition to a few known related examples reported in the scientic literature. [10][11][12][13] These facts strongly motivated us to study, understand, and correlate the inuence of using elemental sulfur on the polymerization of benzoxazines.…”

“…firstly found that benzoxazine can copolymerize with polyfunctional thiol at room temperature. After that, Takeshi and Semiha et al . conducted a series of studies on the reaction conditions and applications of catalytic opening of the lateral benzoxazine rings by thiols (COLBERT reaction).…”

The ring-opening reaction of p-cresol-based 1,3-benzoxazine with amine at room temperature was investigated in different solvents. Results show that the reactions proceeded easily in protic solvents, but no reaction occurred in aprotic solvents. For different amines involved in the reactions, both primary and secondary amines can participate in the reaction with benzoxazine, while tertiary amines would hinder the progress of the nucleophilic reaction. The mechanism study demonstrated the feasibility of polymerization of the benzoxazine with amines at room temperature. Moreover, the crosslinking between bifunctional benzoxazine and diamine was realized at room temperature, and the polymer can be obtained.[a] J. Zong, Q. Ran

“…Another synthetic approach concerning the thiol-oxazine reaction is reported to obtain copolymer from a main-chain PBZ precursor. By selecting the appropriate benzoxazine structure and thiols, desired architectures can be produced for various applications in fast and easy conditions [32]. It was also demonstrated that block copolymers can be prepared by means of successive COLBERT procedures in sequence and one-pot synthesis, and this was suggested as novel thiol-X chemistry [33,34].…”

A catechol-based benzoxazine copolymer is reported via a new approach using an oxazine-thiol reaction. The main chain benzoxazine precursor was obtained via the classic benzoxazine synthesis methodology using the raw chemicals catechol, formaldehyde, and 4,7,10-trioxa-1,13-tridecanediamine. The countercomponent was synthesized from poly(ethylene glycol) methyl ether via the Fischer esterification reaction. The obtained reactive catechol-based benzoxazine was then reacted in mild conditions with polymeric thiol precursor to obtain a copolymer structure. The precursors and the resulting structure were characterized by thermal and spectral analyses using DSC, TGA, FT-IR, 1 H NMR, and GPC. Film formation was also demonstrated with unreacted oxazine ring units in the copolymer, and the ring opening polymerization temperature was lower than that corresponding to the benzoxazine precursor.
