Catalytic activity of silylamide derivatives of three-valent lanthanoids [(Me3Si)2N]3Ln (where Me-CH3; Ln-Pr, Sm, Eu, Gd, Tb, Er, Yb) was studied under conditions of low temperature polymerization of methacrylate. The reaction involved an anion-dependent mechanism and was accompanied by formation of block polymer. The physiological activity of the polymethacrylate produced was manifested as stimulation of the growth rate in bone tissue after its impairments. The organo-element fragment introduced into the polymer was responsible for this kind of activity.
