摘要： A process for producing a benzoxazine containing free aliphatic hydroxyl groups and monoester comprising the steps of: a) a reaction of a phenolic acid derivative with a monofunctional oligomer or molecule at a temperature of from 80° C. to 200° C., during 12 h-48 h, in a presence of a Bronsted type acid catalyst, resulting in a monophenol terminated oligomer or molecule and b) reaction of the monophenol terminated oligomer or molecule of step a) with a mixture of an amino-alcohol, a primary amine derivative and paraformaldehyde at a temperature range of from 80° C. to 100° C., from 1 h to 48 h, under stirring.

摘要： Disulfide-containing benzoxazine monomers of formula I




Also a process for synthesizing a disulfide-containing benzoxazine monomer of formula I comprises the following steps consisting of providing a mixture comprising an amino disulfide compound:H2N—R—NH2, wherein R is as defined for the monomer of formula I, an aldehyde derivative; phenolic derivatives, stirring the mixture under a temperature of from 50° C. to 130° C. for 1 h to 48 h, for obtaining the monomer of formula I; wherein the respective stoichiometry of the amino disulfide compound: aldehyde derivative:phenolic derivatives is 1:4: x1+x2, with x1+x2=2 and 0
