Salts of diorganyl phosphinic acids, method for their manufacture and their application

摘要

Diorganylphosphinic acid-salts and/or diorganyldiphosphinic acid-salts and/or their polymers (A) are new. Diorganylphosphinic acid-salts of formula (I) and/or diorganyldiphosphinic acid-salts of formula (II) and/or their polymers (A) are new (where the total content to the partially water-soluble, ionisable compounds and the water-soluble content of the partially water soluble, ionisable compounds amounts to about 8200 to 100 ppm (preferably 7000 to 200 ppm)). R 1>, R 2>1-6C alkyl and/or aryl; R 3>1-10C alkylene, 6-10C arylene, 6-10C alkylarylene or 6-10C arylalkylene; M : Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Li, Na, K and/or a protonated nitrogenbase; and m, n, x : 1-4. Independent claims are also included for: (1) the preparation of (A); and (2) use of diorganylphosphinic acid salt (I) as flame protective agents or in flame protective composition (preferably in polymers) or for the production of flame-protective polymer molding materials, -films, -threads and -fibers.
