Abstract
Silicon compound of general formula a), in which A, B, C, D are radicals which are different from OH and are covalently bonded to Si; two or three of these bond that are linked to Si are Si—O—C, Si—S—C or Si—N—C type bonds and are hydrolyzable in vivo, forming Si—OH bonds that are biologically active especially when in contact with living tissue, the A and D bonds of formula b) being invariably hydrolyzable; at least one of the hydrolyzable bonds corresponds to an acyloxy, aryloxy or vinyloxy radical; at least one of the compounds obtained after hydrolysis of the hydrolyzable bonds is a stabilizer, and the non-hydrolyzable bonds, which are of the Si—C type, correspond to hydrocarbon or fluorocarbon radicals for which Si is not directly linked to the phenyl ring.
