FIELD: polymeric materials production.
SUBSTANCE: invention relates to a flame-retardant catalyst for the production of polymeric materials based on benzoxazines and a curable composition. This flame retardant catalyst is hexakis-(3-methylphenylamino)cyclophosphazene of the general formula 
. The curable composition includes in pts. wt.: benzoxazine 100; flame retardant catalyst 0.1-40 and epoxy 0-75.
EFFECT: development of a new catalyst capable of forming a covalent bond with polybenzoxazine (and its copolymer with epoxides) during curing simultaneously with performing the functions of a catalyst and a fire retardant.
