Phosphorus-contg. organosilicon cpds. with units of formula (I) are new. R = opt. halogenated 1-18C hydrocarbyl; R' = H, OH, 1-18C hydrocarbyl or a gp. of formula Z =2-18C hydrocarbylene; M = alkali(ne earth) metal; X = halogen or -OR<2> (with R<2> = 1-8C alkyl, opt. substd. with ether oxygen); a = 0, 1, 2, 3 or 4; b, c = 0, 1, 2 or 3; a + b + c = 4; f = 0.5 or 1. Also claimed is the prodn. of these cpds. by reacting (I) organosilicon cpds. of formula (II) with (2) alkali or alkaline earth phosphinate or phosphonate salts of formula (III) in the presence of (3) radical-forming catalysts: B = 2-18C hydrocarbyl gp. contg. aliphatic multiple bonds; R<3> = R<1>. |
