摘要:Flame-retarding composition comprising: 10 - 90 wt. % melem, 0.01 - 30 wt. %melam, 0.01 - 15 wt. % melamine, 0.1 - 65 wt. % higher condensation products ofmelamine and/or melem, the volatiles content being lower than 3 wt. % and the sum ofthe individual components amounting to 100 wt. %. Also a process for the preparation ofa flame-retarding composition comprising 10 - 90 wt. % melem, 0.01 - 30 wt. % melam,0.01 - 15 wt. % melamine and 0.1 - 65 wt. % higher condensation products of melamineand/or melem, the volatiles content being lower than 3 wt. %, by heating melamine-containing starting product fo r more than 0.1 second, for example by passing it througha heating zone, at a temperature of 350 - 800 ~C and a pressure of between 1 KPa and 50Mpa. The invention also relates to polymer compositions containing the flame-retardin gcomposition.
