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 —S
x
—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
一种
硫化苯并噁嗪化合物,可用于合成聚苯并噁嗪,对应于式(A):
其中:两个噁嗪环的每个苯环核上至少带有一个标记为“G”的基团;两个噁嗪环通过一个中央芳香基团连接在一起,该芳香基团的苯环上带有一个、两个、三个或四个形式为—Sx—R的基团,“x”为1至8之间的整数,R代表氢或包括1至10个碳原子的碳氢基团,可选地选择从O、S、N和P中选择的杂原子;至少两个基团G,可以相同也可以不同,从各种基团中选择。
