    摘要： 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.

    摘要： This invention relates to a highly flame-retardant adhesive for high-polymer materials. The adhesive contains a phenolic hydroxyl flame retardant which is prepared from organic amino compounds by one-step reaction with simple and controllable synthesis conditions and high synthesis efficiency; and then the highly flame-retardant adhesive can be obtained by blending the flame-retardant and the adhesive. The highly flame-retardant adhesive synthesized in the invention can be directly used as an adhesive for polymer materials to produce high adhesion strength, or used as a basic formula and prepared into composite adhesives through the addition of other fillers, or used as a primer agent to modify surfaces of polymer materials, so as to meet different needs on various special occasions.
