Complex 5 Is Shown To Be In Equilibrium With The 1,6,2,5-Diazadisila-[6]Ferrocenophane 6. Both Complexes 5 And 6 Were Characterised By X-Ray Structural Analysis,And In Solution By H-1,C-13 And Si-29 NMR Spectroscopy. (C) 2004 Elsevier B.V. All Rights Reserved.

专利号:US-6921802-B2 优先权日:1999-07-27 标题 :Contact lens materials 发明人:KUENZLER JAY F; MARTIN ARTHUR W 权利人:BAUSCH & LOMB 摘要:A method for reducing the modulus of polymer silicone hydrogel compositions by employing monomeric polysiloxanes endcapped with trimethylsilyl to reduce the crosslinking density of the hydrogel. The synthesis consists of a single vessel acid catalyzed ring opening polymerization and may be employed to produce copolymers useful as hydrogel contact lens materials.
