The invention relates to method for producing mono amino-functionalised dialkylphosphonic acids esters and salts, characterised in that a) a phosphinic acid source (I) is reacted with olefins (IV) in the presence of a catalyst A to give an alkylphosphonous acid, the salt or ester thereof (II), b) the alkylphosphonous acid, the salt or ester thereof (II) produced above is reacted with an allylamine of formula (V) in the presence of a catalyst B to give mono amino-functionalised dialkylphosphinic acid derivatives (III) where, R1, R2, R3, R4, R5, R6, R7, R8, R9 independently=amongst others, H, C1-C18 alkyl, C6-C18 aryl, C6-C18 aralkyl, C6-C18 alkylaryl and X═H, C1-C18 alkyl, C6-C18 aryl, C6-C18 aralkyl, C6-C18 alkylaryl, Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Cu, Ni, Li, Na, K and/or a protonated nitrogen base and Y=a mineral acid, a carboxylic acid, a Lewis acid or organic acid, where n=a whole or fractional number from 0 to 4, catalyst A is a transition metal and/or transition metal compound and/or catalyst system comprising a transition metal and/or a transition metal compound and at least one ligand and catalyst B is compounds forming peroxides and/or peroxide compounds and/or azo compounds.
A method for producing monoamino-functionalized dialkylphosphinic acids, esters or salts, comprising the steps of:
A flame-retardant thermoplastic or thermoset polymeric molding material containing 0.5% to 45% by weight of a monoamino-functionalized dialkylphosphinic acid, salt or ester according to claim 1, 0.5% to 95% by weight of a thermoplastic or thermoset polymer or mixtures thereof, 0% to 55% by weight of additives and 0% to 55% by weight of filler or einforc ng materials, wherein the sum total of the components is 100% by weight.
Flame-retardant thermoplastic or thermoset polymeric molded articles, films, threads or fibers containing 0.5% to 45% by weight of a monoamino-functionalized dialkylphosphinic acid, salt or ester according to claim 1, 0.5% to 95% by weight of a thermoplastic or thermoset polymer or mixtures thereof, 0% to 55% by weight of additives and 0% to 55% by weight of filler or reinforcing materials, wherein the sum total of the components is 100% by weight.
