Abstract: Stabilized red phosphorus consisting of particular with a size of at most about 2 mm and an oxidation stabilizer. The individual phosphorus particles are superficially covered with a thin film of a polycondensation product of melamine and formaldehyde as the oxidation stabilizer, the polycondensation product being used in a proportion of about 1 to 20 weight %, based on the quantity of red phosphorus.

Abstract: Aq. melamine/HCHO resins contg. a guanamine (I) are claimed. Pref. (I) is benzoguanamine or 5-17C alkyl-guanamine, esp. caprino-guanamine (IA). The melamine: (I): HCHO molar ratio is 1: (0.001-0.5):(1.3-6). The resin may be (partly) etherified with 1-4C alcohols, esp. using a melamine:alcohol molar ratio of 1:(0.8-6). The resin contains 60-85 wt.% solids. The resin is prepd. by reacting melamine and (I) with HCHO; opt. etherification with a 1-4C alcohol; and adjusting the prod. to the required solids content. (claimed).

Abstract: The invention relates to a particulate agent based on free-flowing pulverulent ammonium polyphosphates of the general formula H(n-m) ? 2(NH4)mPnO3n ? 1 in which n is an integer having an average value of from approximately 20 to 800 and the ratio of m to n is approximately 1, for impeding the combustibility of combustible materials. The agent is comprised of a) approximately 75 to 99 % by weight of ammonium polyphosphate, and b) approximately 1 to 25 % by weight of a hardened melamine and formaldehyde encasing the individual ammonium polyphosphate particles.

Abstract: The invention relates to stabilized, pulverulent red phosphorus, consisting of phosphorus particles having a particle size of at most about 2 mm, and an oxidation stabilizer which envelops the phosphorus particles in the form of a thin layer , whereina) The oxidation stabilizer is a combination of aluminum hydroxide and is a combination of system having an epoxide equivalent weight of about 170 to 500.b) the total amount of the oxidation stabilizer is 0.1-5 % by weight, based on the amount of red phosphorus, andc) the proportion of aluminum hydroxide is about 0.01 to 3 % by weight, and the proportion of epoxide resin is about 0.09 to 4.99% by weight, in each case based on the amount of the red phosphorus.
