Halogen-free flame-retardant composition

摘要

The invention relates to a halogenfree, flame-retardant composition that comprises at least (A) an organic phosphorus compound and (B) melamine or a compound derived from melamine, or a melamine-phosphorus compound (AB) and a polymer compound comprising an olefine having 2-12 carbon atoms and 0.1-30 weight % (relative to the weight of the polymer compound) of a compound containing acid, acid anhydride or epoxy groups. The invention also relates to a polycondensate composition that contains the flame-retardant composition according to the invention. The flame-retardant composition according to the invention presents the advantage that the burning time of the polycondensate composition in which the composition according to the invention is used is substantially shortened. Preferably the flame-retardant composition is used in polyesters or polyamides.
