FIELD: chemistry. n SUBSTANCE: invention relates to organosilicon polymers, containing benzoic acid esters, in form of particles, method of obtaining thereof, thereof-containing cosmetic or dermatological compositions, as well as to their application for protection of human or animal organism from UV-radiation. Method of obtaining polymer compounds of silyl ether by interaction of monomers (I) and (IV) is claimed. Also claimed are: polymer, obtained by said method, versions of its application, polymer composition, as well as monomer (I) for obtaining said polymer and methods of its obtaining. n EFFECT: obtained polymers demonstrate increasing UV-protection depending on time of exposure to sun and radiation intensity. n 15 cl, 12 dwg, 1 tbl, 37 ex |
