The invention relates to mixtures composed of dialkylphosphinic esters and of further components, which comprisen A) from 98 to 100% by weight of monocarboxy-functionalized dialkylphosphinic esters of the formula (I) nn n n n n n n n n n in which R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , and R 7 are identical or different and, independently of one another, are H, methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, and/or phenyl, n Y is methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, phenyl, 2-hydroxyethyl, 2,3-dihydroxypropyl, 2-hydroxypropyl, 3-hydroxypropyl, 4-hydroxybutyl, 3-hydroxybutyl, 2-hydroxybutyl, and/or 6-hydroxyhexyl, allyl, and/or glycerol, n X is H, Li, Na, K or NH 4 , n or X is defined as for Y, and then X and Y are two identical radicals or two different radicals of the above organic radicals, and n B) from 0 to 2% by weight of halogens,n nwhere the entirety of the components always amounts to 100% by weight. |
