METHOD FOR PRODUCING MOULDED HYDROGEL ARTICLES Russian patent published in 1996 - IPC

FIELD: production of mounded hydrogel articles. SUBSTANCE: hydrophilic methacrylaye monomer is mixed with sewing agent and water-displaced diluent with viscosity of 100 MPa at least at 30 C. Diluent concludes boric acid ether and double-atom alcohols, cohesion polar Hansen parameter (σ_p) and cohesion polar parameter of hydrogen coupling of Hansen (σh) are embraced by area of circle located in coordinates σ_p and σ_n amd which has center at σ_n 20,5, σ_p 13 and radius equal to 8.5 within scale of these coordinates. EFFECT: improved quality. 12 cl, 3 dwg, 7 tbl
