The experimental results indi e that organic medium has appropriate viscosity 20 pa·s and the highest thixotropic index 9.35 when its composition is as follows: solvents 80.00 wt
To improve intraocular transparency of collagen matrices hydroxypropyl methylcellulose HPMC was introduced for the first time into cross-linked collagen to form collagen–HPMC composite membranes. Light transmittance and refractive indices of the membranes are enhanced by incorporation of HPMC in comparison to the control of cross-linked collagen membranes.

During the 1970–1980 decade he was also associate professor in macromolecular chemistry at the universities of Grenoble and Lyon. In the early 1980s he became assistant manager of Cemota a subsidiary of IFP created to develop manufacture and commercialize high-performance polymers for the electronic and aerospace industries.
2New smart materials with self-healing properties will provide overall cost savings through high value-added finishes on a variety of substrates. Solvent-based high-solids coating systems continue to be developed. Such coatings have markedly decreased volatile organic content and provide high quality coatings and reduced environmental damage

MC is used as a solvent because of its high vapor pressure 350 mm Hg when compared with other economically viable solvents its high boiling point 39.8 deg C its compatibility with many types of formulations and because it depresses the vapor pressure of high pressure propellants.
The addition of diethylene glycol was conducive to high fluorescent reflectivity and gave good line image quality both in warp and weft directions due to the low viscosity.
