(57) [Summary] Silicon compound represented by the following general formula: (In the formula, A, B, C, and D are groups different from OH bonded to Si by a covalent bond; two or three of these bonds with Si are Si-O-C, Si-S. -C or Si-NC type bond; forms a biologically active Si-OH bond that is hydrolyzable in vivo and, in particular, upon contact with biological tissue, forms bond A of formula b) and D is always hydrolyzable; at least one of the hydrolyzable bonds corresponds to an acyloxy, aryloxy or vinyloxy group; at least one of the compounds obtained after hydrolysis of said hydrolysable functional group is Stabilizers; non-hydrolyzable functional groups are of the Si-C type, corresponding to hydrocarbon or fluorocarbon groups where Si is not directly attached to the phenyl ring). |
