FIELD: chemistry.
SUBSTANCE: invention relates to polysiloxane copolymers with one or two hydrophilic terminal polymer chains and their application for obtaining contact lenses. Claimed is actinically-linked linear polysiloxane copolymer, obtained by mixing hydrophilic vinyl monomer and/or vinylacetate with radical-generating polysiloxane of particular structure with obtaining capable of polymerisation composition, by irradiation of composition by ultraviolet radiation and covalent binding of ethylene-unsaturated group to polysiloxane copolymer with extended chain by realisation of reaction between it and vinyl monomer functionalised by ethylene bond. Also claimed is contact lens, obtained with application of said polysiloxane copolymer.
EFFECT: claimed actinically-linked polysiloxane copolymer can be applied for obtaining contact lenses on the basis of silicon hydrogel, which have hydrophilic surface, without surface processing, carried out after hardening.
