Abstract:
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.
