Patent AT-E399816-T1: [Translated] REACTIVE FLAME RETARDANTS AND FLAME RETARDANT RESIN PRODUCTS

The invention provides a reactive flame retardant which can impart excellent flame retardance to a resin when added to the resin even in a small amount and are freed from bleed out; and a product made of flame-retarded resin obtained by using the same. According to the invention, an organic cyclic phosphorus compound represented by the general formula (I) which has at least one unsaturated group at the end of R 1 is used as the reactive flame retardant. The product made of flame-retarded resin can be obtained by solidifying a resin composition containing the organic cyclic phosphorus compound and then reacting the composition by heating or irradiation with a radiation.
