A sulfurized benzoxazine compound, which is usable for the synthesis of a polybenzoxazin, corresponds to formula (A):
in which: each benzene nucleus of the two oxazine rings bears at least one radical denoted as “G”; the two oxazine rings are connected together via a central aromatic group, the benzene ring of which bears one, two, three or four groups of formula —Sx—R in which “x” is an integer from 1 to 8 and R represents hydrogen or a hydrocarbon-based group including 1 to 10 carbon atoms and optionally a heteroatom chosen from O, S, N and P; and the at least two radicals G, which may be identical or different, are chosen from various groups.
可用于合成聚苯并恶嗪的硫化苯并恶嗪化合物符合式 (A): 其中 两个噁嗪环的每个苯核上至少有一个基团,用 "G "表示;两个噁嗪环通过一个中心芳香基团连接在一起,该芳香基团的苯环上有一个、两个、三个或四个式 -Sx-R 的基团,其中 "x "为 1 至 8 的整数,R 代表氢或包括 1 至 10 个碳原子的碳氢基团,以及可选的一个选自 O、S、N 和 P 的杂原子;至少两个基团 G 可以相同或不同,选自不同的基团。
